Internal IT security threats—whether caused by negligence or malice—are among the most damaging and overlooked risks facing businesses today.
At SkyTide Group, we help organizations identify insider vulnerabilities, implement strong access controls, and train staff to become your first line of defense. This article outlines the risks, warning signs, and steps you can take now to reduce exposure and respond effectively if a threat emerges.

Internal IT Security Threats Are Closer Than You Think
Cyber threats aren’t always external. In many cases, they come from the people you already know—employees, contractors, vendors, or even former staff. 90% of cyber breaches involve human error, and insider incidents can go unnoticed for months.
If your team doesn’t know what to look for—or worse, has unnecessary access—you’re at risk.

What Are Internal IT Security Threats?
An internal IT security threat is any cybersecurity risk that originates from within your organization. There are two main types:
1. The Malicious Insider
They act intentionally. They might be disgruntled, financially motivated, or simply negligent with a grudge. These insiders exploit their access to inflict damage or steal data.
2. The Negligent Insider
These are well-meaning employees who fall for phishing scams, reuse passwords, or bypass security protocols for convenience—leaving you exposed.

Policy is Power: Internal Security Governance Essentials
Technology matters—but policies are what make them effective. To reduce internal IT security threats, every business should establish or revisit these essential governance tools:
🔐 Must-Have Policies:
-
Acceptable Use Policy (AUP) – defines how employees should use business systems and data.
-
Onboarding/Offboarding Checklist – ensures user access is updated or revoked immediately when roles change.
-
BYOD (Bring Your Own Device) Policy – outlines how personal devices must be configured to access company data securely.
-
Access Review Procedures – regularly audit who has access to what, and whether they still need it.
Need help developing these? SkyTide provides policy templates, customization, and compliance consulting to get you started fast.
