The Attack That Skips the Firewall

Companies pour billions into cybersecurity every year, yet plenty of incidents never involve a hacker at all. Anyone who already holds valid credentials, internal knowledge, and the right permissions doesn't need to get past a firewall — they're already inside it. That's the question a growing number of security teams in Germany are asking: why aren't firewalls enough against insider threats? Validato, a background screening and human risk management provider working across more than 200 countries, built its business around exactly this gap.


External attacks can usually be spotted and blocked with the right tools. Insiders are different. Employees, external service providers, and other authorized people move through an organization in ways that look entirely legitimate — because, on paper, they are. That's what makes insider risk a human-risk problem as much as a technical one.

More Than a Bad Actor

"Insider threat" often brings to mind someone deliberately leaking data. That's only part of the picture. Negligence, social engineering, and compromised accounts can just as easily turn legitimate access against a company. And "insider" isn't limited to employees, either — consultants, developers, IT service providers, and freelancers sometimes carry more extensive system permissions than the staff on the org chart. That chart shows who works for a company. It doesn't show who can actually reach its most sensitive information.

Where HR Security Meets IT Security

Cybersecurity answers one set of questions: who can access which systems, what counts as unusual activity, how are privileged accounts monitored. Human risk management asks a different set: who is actually behind the account, has their identity been verified, does their professional background hold up, and which roles carry outsized risk? Put the two together and the model stops being purely technical.


This isn't just Validato's view. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) explicitly highlights the role of HR in detecting and reducing insider risk, since HR touches the entire employee lifecycle — from application to departure. Identity fraud, falsified qualifications, or a misrepresented background won't show up in a firewall log. They need a different kind of process entirely.

Validato's Five-Layer Approach

A resilient security architecture, in Validato's view, needs to cover at least five areas:


• Identity verification to confirm who is actually receiving access before it's granted

• Background screening for risk-relevant positions

• Permissions management tied to real function and need

• Monitoring paired with a security culture that makes reporting easy

• Lifecycle management, since a promotion or move into a sensitive project can call for a fresh risk assessment

Trust, Backed by Verification

None of this is about distrust. It's about building trust on something more solid than assumption. Insider-threat prevention doesn't sit exclusively with HR or exclusively with IT security — it lives at the intersection of both. The strongest security architecture accounts not just for which systems need protecting, but for who gets access to them. Validato runs background checks, identity verification, and human risk management for companies worldwide, giving that intersection a practical, day-to-day shape.
