Insider threats are one of the most persistent and damaging security challenges organizations face today. While many companies invest heavily in perimeter tools and detection technology, a leading cybersecurity expert argues that the real defenses lie in human relationships: trust, culture, and communication.
Ajay Nyayapathi, a principal security engineer with nearly two decades of experience, explains that the people who bypass a company’s defenses are often already inside—disgruntled employees, careless contractors, or well-meaning colleagues who inadvertently leave a door open. “Zero trust starts with people who actually trust each other,” he says.
When Insiders Hold the Keys
Employees click on suspicious links, departing staff copy files “just in case,” and trusted managers write passwords on sticky notes. Firewalls stop outsiders, but insiders have knowledge of systems, routines, and relationships that open doors quietly. Nyayapathi watches for signals others overlook: logins at odd hours, bulk downloads before leave, and files pulled from shared folders in patterns that don’t fit the job.
In one case, a quiet manager siphoned customer records over several months without setting off a single alarm. A colleague’s attention, not a system, caught it. “People don’t set out to betray. They drift when nobody watches,” Nyayapathi notes. The drift appears in small ways: skipped training, quick favors for friends, a mood that sours without anyone asking why.
Culture That Spots Trouble Early
Teams work better when people feel safe speaking up. Nyayapathi builds groups where an engineer can question a risky move without worry, and where a manager notices tension before it escalates. When raising a concern earns respect rather than blowback, people do it more often. He has seen a new hire stop an attempted theft by questioning unusual activity, and a supervisor block a leak by voicing doubts about a departing colleague.
Leaders set the tone by rewarding candor and explaining why a rule exists. Nyayapathi leans on simple charts and data-flow maps so the same threat reads clearly to an engineer and an executive. When people understand the stakes, they treat company data as worth protecting and become more willing to flag a colleague who has wandered off a secure path.
Words That Steady and Sharpen
Clear communication matters most when things go wrong. Nyayapathi breaks an incident into plain steps: who acted, what broke, and what happens next. That structure settles a room. He recalls one flagged download that put a room on edge; he traced its path, found control gaps, and laid out practical fixes. The tension eased once the issue was contained.
He argues daily habits matter more: short huddles that pick apart near-misses, lessons that move freely between engineers and managers, and newer staff learning from experienced colleagues. Open communication catches drift early and heads off breaches before they happen. Dashboards show what’s beneath the noise, and a clear narrative ties the pieces together so everyone sees the same picture.

Four Practical Steps to Strengthen Defenses
Nyayapathi offers four actionable steps for organizations:
- Hold monthly “near-miss” reviews where teams discuss small mistakes openly without assigning blame.
- Have managers, not just HR, check in with departing employees during their final two weeks.
- Map data-flow ownership so every team knows exactly what it is responsible for and why.
- Make small interventions normal—a quick question, a nudge, or a short clarifying conversation—since these minor moments often prevent major incidents.
Nyayapathi remains optimistic about workplaces where trust runs through every level and people protect what they understand. “Technology detects anomalies,” he says. “People detect intent, and intent is where every insider-risk story begins and ends.” His message is consistent: put people first, and the safeguards tend to follow.
