Insider Threat Program
Defend Against the Threat Within
Most security breaches involve an insider - not necessarily a bad actor, but someone with legitimate access who made a mistake, fell for a scam, or simply didn't know better. And as AI tools become part of everyday work, the definition of 'insider threat' has expanded: employees sharing sensitive data with public AI systems now represents one of the fastest-growing unintentional risk categories.
TBDCyber builds insider threat programs that address the full spectrum, from policy and detection to response and culture, tailored to your organization's risk profile and existing technology investments.
Our Tailored Approach Includes
ITM Assessment
& Program Design
-
Assess your current insider threat posture, reviewing existing policies, tooling, monitoring capabilities, and incident history to establish a true baseline.
-
Identify your highest-risk insider threat scenarios based on your specific assets, workforce profile, access model, and industry, including AI tool adoption as an emerging unintentional threat vector.
-
Map your program requirements to applicable regulatory or contractual frameworks, including CMMC, NISPOM, HIPAA, and government contractor obligations where relevant.
-
Define program scope, governance structure, KPIs, and a phased implementation roadmap, so you have a clear, prioritized path from where you are to where you need to be.
Policy, Governance
& Compliance
-
Develop or modernize your insider threat policy framework, covering acceptable use, data handling, AI tool usage, privileged access, and remote work, aligned to your risk appetite and workforce culture.
-
Define a governance structure for your ITP: who owns the program, how cross-functional stakeholders (HR, Legal, IT, Security) collaborate on investigations, and how findings are escalated.
-
Establish privacy-preserving investigation procedures that comply with applicable employment law and balance security monitoring with employee trust (a critical and frequently neglected element).
-
Create clear, legally defensible reporting mechanisms, so employees know how and when to report suspicious behavior without fear of retaliation
Technology Selection & Implementation
-
Evaluate your current technology stack for insider threat coverage, assessing UEBA, DLP, PAM, CASB, and endpoint monitoring tools for gaps, misconfigurations, and underutilized capabilities before recommending anything new.
-
Select and implement the right insider threat detection technologies for your environment (including Microsoft Purview, Microsoft Sentinel with UEBA, Securonix, Varonis, or equivalent platforms) that match your size, budget, and risk profile.
-
Configure behavioral baselines and alert thresholds tuned to your organization to reduce false-positive rates that cause alert fatigue and ensure your team acts on what matters.
-
Enable AI-aware monitoring capabilities that detect sensitive data exfiltration to external AI tools, LLMs, and AI-powered SaaS applications, one of the fastest-growing unintentional insider threat vectors.
Behavioral Monitoring
& Detection
-
Establish continuous behavioral monitoring using UEBA, establishing normal activity baselines for users and entities, then detecting statistically significant deviations that may indicate insider threat activity
-
Define and tune detection scenarios for your most critical assets and highest-risk roles, covering data exfiltration, privilege escalation, unusual access patterns, and AI tool misuse involving sensitive data.
-
Implement a tiered alert model that prioritizes investigation resources on the highest-confidence signals, preventing alert fatigue while ensuring nothing critical is missed.
-
Develop analyst playbooks for initial triage and escalation, so your team knows exactly how to assess, document, and escalate a potential insider threat event consistently and defensibly.

Insider Threat Investigation
& Response
-
Develop insider threat-specific incident response playbooks that cover the full investigation lifecycle, from initial alert triage through evidence preservation, containment, HR and Legal notification, and remediation.
-
Define clear roles and decision rights during an insider threat investigation, including who leads, who is notified at each stage, and how to maintain confidentiality while coordinating across HR, Legal, Security, and management.
-
Conduct tabletop exercises to rehearse insider threat scenarios, testing your team's readiness to respond decisively when a real incident occurs, including AI-assisted exfiltration.
-
Perform structured post-incident reviews to identify how the threat was possible, what detection gaps existed, and what program changes would prevent recurrence, converting each incident into a program improvement.
Culture, Awareness
& Deterrence
-
Deliver insider threat-specific awareness training that explains the spectrum of insider risk (from malicious actors to unwitting accomplices and negligent employees), so staff understand that insider threat isn't just about "bad people".
-
Train employees on the safe use of AI tools as a core component of insider threat prevention, covering which data must never be shared with public AI systems and how to recognize and report AI-related data-handling concerns.
-
Implement deterrence messaging alongside awareness, communicating clearly that monitoring is in place, that the organization takes insider threats seriously, and that reporting mechanisms are available and safe to use.
-
Build ongoing reinforcement into the program: role-specific training for high-risk employees, annual refreshers, and scenario-based exercises that keep insider threat top of mind without creating a culture of fear or distrust.
Benefits
Reduce Risk
Build detection and deterrence capabilities that catch insider threats (malicious and unintentional) before sensitive data leaves your environment.
Proactive Threat Detection
Move from reactive investigation to continuous behavioral monitoring, detecting anomalies, including AI-assisted data exfiltration and unusual access patterns, before they escalate.
Faster, Cleaner Response
When an insider incident occurs, a rehearsed playbook means your team acts quickly and consistently, containing damage, preserving evidence, and meeting notification requirements.
Stronger Security Culture
The best insider threat defense is a workforce that understands the risks, knows what to report, and trusts that the organization handles investigations fairly and proportionately.
