The human factor in cybersecurity remains one of the biggest challenges facing businesses in 2026.
Companies are spending heavily on firewalls, endpoint protection, cloud security, identity systems and artificial intelligence. Yet attackers continue to look for something much simpler: a person who can be persuaded to make a mistake.
That might mean clicking a malicious link.
It could involve approving a fraudulent payment.
Sometimes it is simply reusing a password.
In other cases, an employee may accidentally share sensitive information with the wrong person.
The technology protecting an organisation can be extremely sophisticated. However, one convincing social-engineering message can still create an opening.
There is an important nuance, though.
Employees are not literally the “weakest link” in every breach. Verizon’s 2026 Data Breach Investigations Report found that vulnerability exploitation has now overtaken stolen credentials as the leading breach entry point, accounting for 31% of breaches. At the same time, Verizon reports that mobile social-engineering attacks are succeeding at rates 40% higher than traditional email phishing.
So the real problem is not simply careless employees.
It is the interaction between people, technology, processes and increasingly sophisticated attackers.
🔑 Key Highlights
- Human behaviour remains a major component of cybersecurity risk.
- Phishing is evolving beyond traditional email.
- Mobile devices are becoming increasingly attractive targets.
- Social engineering exploits trust rather than software vulnerabilities.
- Employees can accidentally expose sensitive information without malicious intent.
- Security awareness training alone is not enough.
- Strong identity controls can reduce the damage caused by compromised accounts.
- AI is making social-engineering campaigns more convincing and scalable.
- Companies need security systems that assume people will occasionally make mistakes.
- A strong security culture is becoming as important as security technology.
Why Humans Are Still Part of the Security Problem
Cybersecurity teams often talk about vulnerabilities.
They talk about outdated software.
They discuss exposed servers.
They monitor suspicious network traffic.
Yet people create another type of vulnerability.
Unlike software, humans can be influenced.
An attacker can create urgency.
They can impersonate authority.
They can exploit fear.
They can create curiosity.
They can pretend to be a colleague.
They can even build a convincing story around a completely fake situation.
This is the foundation of social engineering.
And it remains highly effective because cybersecurity is not only a technical problem.
It is also a human behaviour problem.
The Employee Is Not the Enemy
This distinction matters.
Calling employees the “weakest link” can create the wrong culture.
If people are afraid of being blamed after making a mistake, they may avoid reporting incidents.
That can make a small problem much worse.
Imagine an employee clicks a suspicious link.
They realise something feels wrong.
If the company has a blame-first culture, they may stay silent.
Meanwhile, the security team does not know that credentials may have been exposed.
A better approach encourages employees to report suspicious activity quickly.
Verizon has highlighted this idea in its research on employee self-reporting, noting that organisations can benefit when employees feel comfortable reporting suspicious messages and mistakes instead of hiding them.
Therefore, the goal should not be:
“Never make a mistake.”
It should be:
“Make mistakes harder to exploit, and report them quickly when they happen.”
Phishing Has Changed
Phishing remains one of the oldest tricks in cybersecurity.
The basic idea is simple.
An attacker pretends to be someone trustworthy.
The target is encouraged to click, respond, provide information or take another action.
However, modern phishing is becoming more sophisticated.
Attackers can personalise messages.
They can imitate corporate language.
They can create convincing fake login pages.
They can use information from social media.
They can combine email with phone calls or text messages.
The objective is to make the interaction feel normal.
That is why simply telling employees to “watch out for suspicious emails” is no longer enough.
The Mobile Problem Is Growing
The workplace has moved beyond the desktop.
Employees use:
- Smartphones
- Tablets
- Messaging applications
- Collaboration tools
- Mobile email
- Personal devices
Consequently, attackers are moving there too.
Verizon’s 2026 DBIR reports that mobile social-engineering attacks have click rates 40% higher than traditional email phishing. The report points to fake texts and scam calls as part of the shift.
That is significant.
People have become better at recognising suspicious email patterns.
However, an unexpected text message or phone call can feel more personal.
A message saying:
“Your manager needs this urgently.”
can create pressure before the recipient has time to think.
Social Engineering Exploits Trust
The technology behind a social-engineering attack can be surprisingly simple.
The difficult part is often the story.
Attackers may pretend to be:
- A manager
- A supplier
- A bank
- An IT administrator
- A colleague
- A customer
- A government agency
The target does not necessarily need to be technically confused.
They simply need to trust the wrong person.
That is what makes social engineering dangerous.
The Psychology Behind the Attack
Social engineering often relies on predictable human reactions.
Urgency
“Do this immediately.”
Authority
“This request is from your manager.”
Fear
“Your account will be suspended.”
Curiosity
“Look at this confidential document.”
Familiarity
“This is your usual supplier.”
Reward
“You have been selected for a benefit.”
These techniques work because they exploit normal human behaviour.
People are designed to respond to social cues.
Cybersecurity attackers understand that.
Business Email Compromise Is Still a Serious Problem
Business email compromise, or BEC, is a particularly damaging form of social engineering.
The attacker attempts to manipulate a business transaction.
For example, a fraudulent request may appear to come from an executive or trusted supplier.
The message could request a payment.
It could ask for account information.
It could instruct an employee to change banking details.
The technology does not necessarily need to be complicated.
The deception does the work.
Verizon describes BEC as a form of social engineering that targets trust and can generate significant financial losses.
AI Is Making Social Engineering More Convincing
Artificial intelligence is changing the human factor problem.
Attackers can use AI to generate convincing messages more quickly.
They can adapt language.
They can translate content.
They can create personalised communications.
They can analyse publicly available information.
They can generate synthetic voices and other deceptive media.
The result is a growing challenge.
A suspicious message may no longer contain obvious spelling mistakes.
It may look professional.
It may sound natural.
It may reference real information about the target.
Verizon’s 2026 DBIR reports that generative AI is being used to augment attack techniques and says 15% of attack techniques in its dataset were bolstered by generative AI.
The era of spotting phishing simply because “the grammar looks bad” is ending.
Deepfakes Add Another Layer
AI-generated audio and video create an even bigger problem.
Imagine receiving a voice message that sounds like a senior executive.
The voice asks for an urgent action.
The employee recognises the voice.
They trust it.
But the audio is synthetic.
The same problem can occur with video.
As generative AI improves, organisations will need stronger verification processes.
The question can no longer be:
“Does this sound like my boss?”
It needs to become:
“How do I independently verify this request?”

Passwords Still Matter
Passwords may appear old-fashioned.
However, they remain an important part of the security problem.
Employees may:
- Reuse passwords
- Choose predictable passwords
- Share credentials
- Store passwords insecurely
- Ignore security warnings
- Approve unexpected login requests
Stolen credentials can then provide attackers with legitimate access.
Verizon’s 2026 DBIR says vulnerability exploitation has surpassed stolen credentials as the leading breach entry point. However, credential abuse remains a major concern, particularly when combined with social engineering.
The lesson is not that passwords no longer matter.
The lesson is that companies need stronger identity protection.
Multi-Factor Authentication Changes the Equation
Multi-factor authentication adds another layer between an attacker and an account.
If a password is stolen, MFA can make unauthorized access more difficult.
However, MFA itself can be targeted.
Attackers may try to convince users to approve fraudulent authentication requests.
Therefore, organisations should combine MFA with:
- Strong identity policies
- Device controls
- Risk-based authentication
- Login monitoring
- User education
- Phishing-resistant authentication where appropriate
Security should not depend on one control.
Employees Can Accidentally Leak Data
Not every security incident begins with an attacker.
Sometimes the employee makes a simple mistake.
A document is sent to the wrong recipient.
A confidential file is uploaded to the wrong location.
A customer database is accidentally shared.
A laptop is left unsecured.
A sensitive document is printed and misplaced.
These incidents may not involve malicious intent.
Yet the consequences can still be serious.
Verizon’s definition of the human element includes both malicious and non-malicious behaviour, such as errors and privilege misuse.
Shadow AI Creates a New Human Risk
Artificial intelligence has introduced another problem.
Employees increasingly use AI tools to summarise documents, analyse information, write code or improve productivity.
That can be useful.
However, employees may upload sensitive company information into an AI service without understanding how the data is handled.
This is sometimes called shadow AI.
The problem is not necessarily the employee’s intention.
They may simply be trying to work faster.
The security risk comes from using an unapproved service without understanding the consequences.
Verizon’s 2026 DBIR reports that employee use of unapproved “shadow AI” had tripled to 45% in its dataset, highlighting the growing connection between AI adoption and data leakage risk.
Companies therefore need clear AI-use policies.

Remote Work Has Expanded the Attack Surface
The traditional office had a clear boundary.
Employees worked on company networks.
Devices were often managed centrally.
Security teams could control the environment more easily.
Remote and hybrid work changed that model.
Employees now work from:
- Homes
- Hotels
- Airports
- Cafés
- Co-working spaces
- Personal devices
That flexibility has benefits.
However, it also creates new risks.
A compromised home router.
An unsecured device.
A shared computer.
A public network.
A stolen laptop.
Any of these can become part of a wider attack.
Why Security Training Alone Does Not Work
Many organisations respond to human risk with one solution:
Training.
Employees attend a cybersecurity course.
They answer questions.
They receive a certificate.
Then everyone returns to work.
The problem is that cybersecurity behaviour does not change permanently because someone watched a presentation.
Verizon has warned against treating training alone as proof that an organisation is secure. Its 2026 guidance argues that organisations need broader measures because training does not automatically translate into secure behaviour.
Training is useful.
But it needs to be part of a larger strategy.
Security Should Be Designed Around Human Behaviour
This is where many companies get the approach wrong.
They expect employees to behave perfectly.
A better approach assumes that people will occasionally make mistakes.
Then security controls reduce the consequences.
For example:
If someone clicks a malicious link, endpoint security can block the payload.
If credentials are stolen, MFA can prevent access.
If an unusual login occurs, identity systems can flag it.
If sensitive data is being uploaded, data-loss prevention controls can intervene.
If an employee reports a suspicious message, security teams can investigate it.
The system becomes resilient because it does not depend entirely on perfect human behaviour.
Make the Secure Choice the Easy Choice
Employees are more likely to follow security rules when those rules fit naturally into their work.
Consider password management.
If employees are expected to remember dozens of passwords, they may reuse them.
A password manager makes the safer behaviour easier.
Similarly, if reporting phishing requires sending an email to a complicated address, employees may not bother.
A simple “Report Phishing” button can change that.
The principle is straightforward:
Good security should reduce friction, not create unnecessary friction.
Build a Culture of Reporting
Security teams need information.
Employees are often the first people to notice something unusual.
They may see:
- A suspicious email
- An unexpected login alert
- A strange payment request
- An unfamiliar file
- A strange phone call
- An unusual message from a colleague
If they report it quickly, the security team may be able to stop the problem.
If they stay silent, the attacker gets more time.
Therefore, companies should reward responsible reporting rather than punish honest mistakes.
Executives Are Targets Too
Cybersecurity training often focuses on ordinary employees.
That is not enough.
Executives can be particularly attractive targets because they may have:
- Financial authority
- Access to sensitive information
- Broad permissions
- Public profiles
- Influence over employees
An attacker impersonating a senior executive can create powerful social pressure.
Therefore, executives need strong security practices too.
No one should be considered “too senior” for cybersecurity controls.
IT Teams Are Not Immune
Security professionals can also make mistakes.
They may misconfigure systems.
They can approve the wrong access.
They may overlook an alert.
They can fall for sophisticated social engineering.
The difference is that privileged technical accounts can have much greater consequences.
Therefore, administrator accounts require particularly strong controls.
Privileged Access Is a Special Risk
Not every employee has the same level of access.
An administrator may be able to:
- Change security settings
- Access databases
- Modify user accounts
- Deploy applications
- Disable controls
If that account is compromised, the attacker may gain significant control.
Consequently, organisations should protect privileged accounts with stronger authentication, limited access and detailed monitoring.
The Human Factor Includes Insiders
Not every insider threat is malicious.
There are three broad categories worth considering:
Accidental insiders
Employees who unintentionally cause a security incident.
Negligent insiders
Employees who repeatedly ignore security policies.
Malicious insiders
People who deliberately misuse access.
Each category requires a different response.
Training may help accidental behaviour.
Controls and accountability can reduce negligent behaviour.
Monitoring and access management are particularly important for malicious activity.
Security Teams Need Better Context
A security alert by itself may not tell the whole story.
Consider a login from an unusual location.
That could be an attack.
Or the employee could be travelling.
Similarly, downloading a large file could be suspicious.
Or the employee could be preparing a legitimate business report.
AI can help security teams analyse these patterns.
However, context still matters.
Security systems should distinguish between unusual and malicious behaviour.
Zero Trust Reduces Human Risk
Zero Trust is based on a simple principle:
Do not automatically trust a user or device simply because it is inside the corporate environment.
Access should be continuously evaluated.
That means organisations can consider:
- Identity
- Device health
- Location
- Risk level
- Application
- Data sensitivity
- Behaviour
This approach can reduce the damage caused by compromised accounts.
Why Behavioural Security Matters
Traditional cybersecurity often asks:
“Is this account legitimate?”
Modern security increasingly asks:
“Is this behaviour legitimate?”
That is an important difference.
A legitimate employee may suddenly behave in a way that does not match their normal pattern.
For example:
A finance employee suddenly downloads thousands of files.
An employee logs in from an unusual location.
An administrator accesses systems outside their normal responsibilities.
These signals can help security teams identify potential compromise.
Employees and AI Will Work Together
AI is not simply a threat to employees.
It can also help them.
AI assistants can:
- Summarise security warnings
- Explain suspicious messages
- Help identify risky behaviour
- Assist with security training
- Provide faster answers to security questions
- Help employees report incidents
This creates an opportunity.
Instead of expecting every employee to become a cybersecurity expert, organisations can give employees intelligent tools that help them make safer decisions.
The Future of Security Training Is More Personal
Generic annual training may become less useful.
Instead, organisations can move toward continuous learning.
For example:
An employee repeatedly receives suspicious messages.
The system can provide targeted guidance.
A developer makes repeated security mistakes.
Training can focus on secure development.
A finance employee faces payment fraud.
Training can focus on business email compromise.
This makes security education more relevant.
Companies Should Measure Behaviour, Not Attendance
A completed training course is not necessarily a security improvement.
Companies should ask:
- Are employees reporting suspicious messages?
- Are phishing click rates declining?
- Are risky permissions being reduced?
- Are users adopting MFA?
- Are incidents being reported faster?
- Are employees following data-handling policies?
These measures provide more useful information.
What Companies Should Do Now
Reducing human-related cyber risk requires several layers.
1. Strengthen Identity
Use strong authentication.
Review access regularly.
Remove unnecessary privileges.
2. Protect Mobile Devices
Because mobile social engineering is growing, smartphones should receive the same security attention as laptops.
3. Train Continuously
Use short, practical training rather than relying only on annual presentations.
4. Make Reporting Easy
Employees should be able to report suspicious activity quickly.
5. Protect Privileged Accounts
Administrators and executives require stronger controls.
6. Control AI Usage
Create clear policies for approved AI tools and the types of company information employees can share with them.
7. Use Phishing-Resistant Authentication
Where practical, organisations should adopt stronger authentication methods that reduce the effectiveness of credential theft and social engineering.
8. Monitor Behaviour
Look for unusual access patterns and account activity.
9. Build a No-Blame Reporting Culture
Employees should feel safe reporting mistakes quickly.
10. Design for Failure
Assume that someone will eventually click the wrong thing.
Then build controls that prevent that mistake from becoming a breach.
The Biggest Lesson: People Need Security, Not Blame
The phrase “weakest link” can be useful.
However, it can also be misleading.
An employee is not inherently a security vulnerability.
The real vulnerability appears when an organisation expects people to defend themselves against increasingly sophisticated attacks without giving them adequate tools.
A worker should not have to recognise an AI-generated deepfake perfectly.
A finance employee should not have to identify every sophisticated payment scam.
A developer should not have to remember every security rule.
Technology should help.
Processes should help.
Security teams should help.
The Future Is Human + Machine
Cybersecurity is moving toward a hybrid model.
Machines are good at:
- Processing data
- Detecting patterns
- Monitoring systems
- Automating repetitive tasks
Humans are good at:
- Judgement
- Context
- Creativity
- Decision-making
- Understanding organisational priorities
The strongest security strategy combines both.
AI should not replace people.
People should not have to fight AI-powered attackers without AI-powered defence.
The Human Factor in the AI Era
AI has changed the cybersecurity equation.
Attackers can work faster.
Messages can become more convincing.
Fake identities can become more realistic.
Social engineering can become more personalised.
At the same time, defenders have access to better detection and analysis tools.
That means the human factor is not disappearing.
It is becoming more important.
The employee may be the person who receives the attack.
The employee may also be the first person who notices it.
That distinction matters.
Conclusion
The human factor in cybersecurity remains one of the most important risks companies face.
But calling employees the weakest link tells only half the story.
Modern cyberattacks increasingly combine technology with psychology.
Attackers exploit software vulnerabilities.
They steal credentials.
They target mobile devices.
They impersonate trusted people.
They use AI to increase speed and scale.
Verizon’s 2026 DBIR shows that vulnerability exploitation has now become the leading breach entry point. However, human-centred attacks remain significant, with mobile social engineering showing particularly strong success rates.
The answer is not to blame employees.
Instead, organisations need to build systems that expect human mistakes and limit their consequences.
That means stronger identity controls.
Better authentication.
Continuous security education.
Simple reporting mechanisms.
AI governance.
Behaviour monitoring.
And a culture where employees are encouraged to speak up when something goes wrong.
Ultimately, the strongest security strategy is not one where employees never make mistakes.
It is one where a human mistake does not automatically become a security breach.

Frequently Asked Questions
Why are employees considered a cybersecurity risk?
Employees interact directly with emails, applications, data and external contacts. Attackers can exploit those interactions through phishing, social engineering, credential theft and other techniques.
Are employees really the weakest link?
Not always. Cybersecurity is a system-wide problem. Verizon’s 2026 DBIR found that vulnerability exploitation has overtaken stolen credentials as the leading breach entry point. However, human-centred attacks remain significant.
How is AI changing employee cybersecurity risks?
AI can make fraudulent messages, impersonation attempts and social-engineering campaigns more convincing and easier to scale. It also creates new risks when employees use unapproved AI tools with sensitive company data.
Is cybersecurity training enough?
No. Training is important, but organisations also need strong identity controls, authentication, monitoring, access management, secure technology and effective incident-response processes.
How can employees help improve cybersecurity?
Employees can use strong authentication, follow company security policies, verify unusual requests, avoid sharing sensitive information with unapproved services and report suspicious activity quickly.
What should companies do when an employee makes a security mistake?
The priority should be containment and learning. The organisation should investigate what happened, limit the damage, support the employee in reporting the incident and improve controls so the same mistake is less likely to cause harm again.
