Insider threats are often associated with deliberate actions: an employee stealing confidential information, abusing privileged access, or intentionally sharing sensitive data outside the organization. But malicious intent is only one part of the problem.

Insider risk can also come from employees and contractors who have legitimate access to information but expose it through mistakes, negligence, or unsafe handling. In fact, the 2026 Cost of Insider Risks Global Report found that 53% of insider-risk incidents were linked to employee negligence.

Insider Threat Awareness Month is an opportunity to broaden the conversation beyond deliberate misuse. Stronger insider-risk programs also need to account for what happens when trusted users make mistakes while working with sensitive information.

Why Insider Threats Remain a Serious Cybersecurity Risk

An insider does not need to bypass an organization’s security perimeter. Employees, contractors, partners, and privileged users may already have access to systems and information as part of their normal responsibilities.

That makes insider incidents particularly challenging to identify and contain.

According to the 2026 Cost of Insider Risks Global Report, insider-risk incidents cost organizations an average of $19.5 million annually. The average time required to contain an incident is 67 days, while only 13% are contained within 30 days.

But insider risk is not a single type of threat.

A malicious insider may deliberately misuse legitimate access to steal or expose information. A compromised employee account can allow an external attacker to operate using trusted credentials. And a negligent insider may create exposure without intending to cause any harm.

It is this last category that makes the human element so important to the insider-threat conversation.

More than half of the incidents covered by the 2026 research were associated with employee negligence, demonstrating that insider risk cannot be addressed only by looking for malicious behavior. Sometimes, the security incident begins with an ordinary action by an ordinary user.

Human Error Is a Major Part of Insider Risk

People make hundreds of decisions while interacting with corporate information every day: what to open, where to save it, who to share it with, which application to use, and how to handle it once it becomes accessible.

Most of these actions are routine. They can also create risk.

IBM research found that 74% of CISOs identified human error as their top cybersecurity risk. In the same research, negligent insiders or employee carelessness were the most frequently cited cause of data-loss events, reported by 42% of respondents.

The reasons behind accidental insider incidents can also be surprisingly ordinary.

Employees work under pressure. They become tired or distracted. They misunderstand security requirements. They prioritize completing a task quickly. They may not recognize the sensitivity of the information they are handling or fully understand the consequences of a particular action.

The result can be anything from sending information to the wrong recipient to using an unauthorized application or exposing confidential information to someone who should not see it.

Security awareness and training remain important ways to reduce these behaviors. But organizations cannot build their security strategy on the assumption that every person will make the correct decision every time.

Security controls also need to account for the reality of human behavior.

That becomes especially important once sensitive information has already been accessed and is visible to the user.

When Human Error Becomes a Visual Data Security Risk

Many accidental insider incidents happen during routine work. Employees move between applications, join virtual meetings, work from different locations, handle confidential documents, and share information with colleagues throughout the day.

These everyday interactions create another dimension of human risk: what users can see, capture, expose, or reproduce while working with sensitive information.

A screen shared too broadly can reveal confidential information. Sensitive content can remain visible to people nearby. A screenshot can capture more information than intended. Printed documents can be misplaced or left exposed. Mobile devices can display confidential information in environments the organization cannot fully control.

None of these situations requires malicious intent. They can result from distraction, convenience, poor judgment, or a simple mistake.

Visual exposure can also be intentional. An employee may deliberately photograph sensitive information, capture protected content, or reproduce information they are permitted to view.

This means accidental and malicious insider threats can converge at the same point: the moment sensitive information is visible and a person decides, intentionally or unintentionally, what happens to it next.

This is where visual data security becomes relevant to mitigating insider risks. It introduces controls specifically for sensitive information being viewed and used, where human behavior can create exposure even within otherwise legitimate workflows.

Designing Visual Data Security Around Human Behavior

Human error cannot be eliminated entirely. Organizations can, however, reduce the opportunities for mistakes to turn into serious data exposure.

Visual data security does not replace existing access controls, DLP, encryption, or employee awareness programs. It is to extend protection into the environments where authorized users are actively interacting with sensitive information.

Dynamic screen watermarking, for example, can keep user or session information visible over sensitive content. This reinforces awareness that the information is protected while also providing attribution that can deter intentional misuse.

Screen-capture controls can restrict common methods of capturing information from protected environments, reducing reliance on the user making the correct decision every time.

Similar protections can extend to web applications and mobile devices, while printing controls and watermarking help maintain accountability when sensitive information moves from a digital environment to a physical document.

These controls address both sides of insider risk. For negligent users, they can reduce opportunities for accidental exposure and reinforce secure handling at the moment information is being used. For malicious insiders, visible attribution and restrictions on capture can make deliberate misuse more difficult and increase accountability.

Insider Threat Awareness Should Extend to Data in View

Insider Threat Awareness Month is an opportunity to look beyond the traditional image of the malicious employee.

Intentional misuse remains a serious concern, but insider risk also comes from the everyday decisions of trusted users who are simply doing their jobs.

As organizations give employees access to increasing volumes of sensitive information across applications, devices, and working environments, the human element will remain part of the security challenge.

For organizations strengthening their insider-risk programs, protecting data in view is an important part of addressing the human element of cybersecurity.
