When you think about a cyberattack, you probably picture a hacker somewhere far away trying to break into your network.
But sometimes, the risk is already on the inside.
Employees, vendors, contractors and other trusted users may already have access to your systems and data. That access can create risk, whether someone abuses it intentionally or simply makes an honest mistake.
CISA defines an insider threat as the potential for someone with authorized access or knowledge of an organization to cause harm, either intentionally or unintentionally. Defining Insider Threats [cisa.gov]
The important word there is unintentionally.
Not every insider threat is a bad employee. Sometimes, it’s a good employee making a bad click, sharing information in the wrong place or having more access than they actually need.
6 Insider Risks Every Business Should Know
- Data Theft
Sensitive company or customer information can be copied, downloaded or shared without authorization.
Whether it’s client information, financial records or other confidential business data, once it leaves your control, the damage can be difficult to undo.
- Sabotage
Not every insider threat is accidental.
Someone with legitimate access may intentionally delete files, interfere with systems or otherwise disrupt operations. CISA specifically identifies sabotage and theft among the ways insider threats can present themselves. Defining Insider Threats [cisa.gov]
- Too Much Access
Does everyone in your business really need access to everything?
Probably not.
Access should match the employee’s actual role and responsibilities. The fewer unnecessary doors you leave unlocked, the fewer opportunities there are for sensitive information to end up somewhere it shouldn’t.
- Human Error
This may be one of the easiest risks to overlook because there’s no bad intent involved.
An employee might mishandle data, ignore a security procedure, click something they shouldn’t or accidentally share sensitive information.
The person isn’t the problem. The lack of safeguards is.
- Password Sharing
“Can I quickly use your login?”
It sounds harmless.
But shared credentials make it harder to control who has access to what and can expose the business to unnecessary security risks.
Passwords should stay personal, and businesses should add strong authentication wherever appropriate.
- Unapproved AI Tools
Here’s the newer risk every business should be talking about.
An employee finds an AI tool that makes their job easier. Great! The problem starts when sensitive company, employee or customer information gets pasted into a tool that the business hasn’t reviewed or approved.
The employee may simply be trying to save time, without realizing what they’re sharing.
That’s why businesses need clear guidelines around which AI tools employees can use and what information should never be entered into them. CISA’s September 2026 update to its Insider Threat Mitigation Guide specifically addresses evolving considerations including artificial intelligence and hybrid and remote work.

Warning Signs Worth Paying Attention To
Insider risk isn’t about spying on your employees.
It’s about having the right systems in place to recognize unusual activity and protect both your people and your business.
Things worth investigating may include:
- Unusual access: Someone begins accessing sensitive information that doesn’t appear relevant to their role.
- Large data transfers: Significant amounts of company information are unexpectedly downloaded or moved.
- Repeated access requests: Someone regularly asks for permissions unrelated to their responsibilities.
- Unapproved devices: Sensitive business information is being accessed or stored on devices that haven’t been approved.
- Disabled security controls: Security protections are unexpectedly switched off or bypassed.
- Unapproved AI use: Sensitive business information is being entered into AI platforms that your company hasn’t reviewed or authorized.
And remember:
One unusual event doesn’t automatically mean you have a malicious insider. Context matters.
The goal should be to investigate security events appropriately, not make assumptions about an employee’s intent.
How Do You Protect Your Business From the Inside?
You don’t need to make employees feel like they’re being watched.
Instead, build security around the way they work.
Give people the access they need, not everything they might need
Regularly review access and permissions as employees change roles, responsibilities or leave the organization.
Strengthen account security
Use strong authentication measures and avoid shared credentials wherever possible.
Train your team
Cybersecurity awareness shouldn’t be a once-a-year checkbox. Help employees understand phishing, password security, sensitive data handling and newer risks such as AI.
Set Clear AI Ground Rules
Employees need to know which AI platforms are approved and what company or customer information can and cannot be shared.
Protect Your Data
Maintain appropriate backups and a plan for recovering important business information if something goes wrong.
Have a Plan Before You Need One
Know how your business will respond when suspicious activity, inappropriate access or a potential security incident is identified.
Being prepared is much easier than figuring it out during an emergency.
Good Cybersecurity Starts on the Inside
Protecting your company isn’t about assuming that your employees can’t be trusted.
It’s about recognizing that people make mistakes, access can be misused and technology keeps changing.
