Why reporting suspicious activity is one of the most effective security controls your organization has

Every Report Matters

Security incidents rarely begin with sophisticated attacks. More often, they start with something that simply doesn't seem right—a suspicious email, an unfamiliar visitor, an unexpected password reset notification, or unusual computer behavior.

In those moments, it's easy to dismiss the concern or assume someone else will report it.

That's exactly what cybercriminals count on.

One of the most effective security controls any organization has isn't a firewall or monitoring platform—it's employees who are willing to speak up when something feels unusual.

Why Reporting Matters

Many people worry about wasting the security team's time or raising a false alarm.

In reality, security professionals would much rather investigate dozens of harmless reports than miss the one legitimate threat that could lead to a data breach, ransomware attack, or financial loss.

Early reporting allows organizations to:

• Identify and contain threats more quickly
• Reduce the impact of security incidents
• Improve email filtering and detection capabilities
• Identify recurring attack patterns
• Strengthen employee awareness and training

Even when an incident turns out to be benign, it provides valuable information that helps improve an organization's overall security posture.

What Should Raise a Red Flag?

While not every unusual event represents a security incident, certain situations should always receive additional attention.

Digital Threats

Be alert for:

• Unexpected emails requesting urgent action
• Sender addresses that don't match the organization they claim to represent
• Suspicious links or unexpected attachments
• Password reset notifications you didn't request
• Unexpected login prompts
• Unusual pop-ups or application behavior

Physical Security

Don't overlook physical warning signs, including:

• Visitors without visible identification
• Individuals following others through secure doors without authorization
• Unattended devices in secure areas
• Unauthorized access to restricted locations

Device Behavior

Unexpected system behavior may also indicate a problem:

• Significant performance slowdowns
• Applications opening unexpectedly
• Security software becoming disabled
• Files disappearing or changing without explanation

When in Doubt, Report It

The most important rule is simple:

If something doesn't seem right, report it.

Whether it's an unusual email, suspicious device behavior, or a potential physical security concern, reporting allows your security team to investigate before a small issue becomes a larger incident.

There is no penalty for reporting a concern in good faith.

The greatest security risk is often not reporting something that turns out to be important.

Final Thought

Strong cybersecurity isn't built solely through technology. It's built through awareness, communication, and a culture where employees feel empowered to report concerns without hesitation.

Every report strengthens your organization's ability to detect threats, improve defenses, and protect the people, systems, and information that matter most.
