Insider Threat
Assessment
Structured assessment of your organisation's exposure to malicious, negligent, and compromised insider threats — across access controls, detection capability, data protection, and organisational culture.
Insider threat is one of the most difficult risk categories for organisations to manage — not because the threat actors are especially sophisticated, but because trusted individuals with legitimate access operate inside the defensive perimeter. Existing security controls are largely designed to detect and stop external attackers. Against insiders, they often fail silently.
Levantis Cyber conducts structured insider threat assessments that evaluate your exposure across three insider profiles: the malicious insider (intentional harm or exfiltration), the negligent user (accidental data loss or security failure), and the compromised insider (a legitimate user whose access has been taken over by an external attacker).
Our assessments are grounded in established frameworks (CISA, NIST, ISO/IEC 27001), delivered with sensitivity to the organisational and HR context, and structured to produce practical, prioritised findings — not just a theoretical risk register.
Threat Modelling & Scoping
Development of a threat model specific to your organisation — identifying high-risk roles, sensitive asset categories, likely exfiltration scenarios, and the insider profiles most relevant to your sector and operational context. Scoping establishes which controls and processes will be assessed, and the boundaries of the engagement.
Access Control & Privilege Review
Assessment of how user access rights are provisioned, maintained, and revoked. Identification of over-privileged accounts, dormant accounts, shared credentials, access to sensitive assets without business justification, and the effectiveness of your joiner-mover-leaver processes. Review of privileged access management where applicable.
Data Protection & DLP Assessment
Review of data classification, handling policies, and technical data loss prevention controls. Assessment of whether sensitive data can be exfiltrated via email, removable media, cloud storage, printing, or screen capture — and whether existing DLP controls would detect or prevent realistic exfiltration scenarios aligned to your threat model.
Detection & Monitoring Capability
Evaluation of your ability to detect insider threat behaviour — through SIEM log coverage, user and entity behaviour analytics (UEBA), alerting on data exfiltration indicators, monitoring of privileged user activity, and investigation capability. Gap analysis against the behavioural indicators associated with each insider threat profile.
Policy & Culture Review
Assessment of whether your policies, HR processes, and organisational culture support effective insider threat management — acceptable use, disciplinary procedures, pre-employment screening, exit processes, whistleblowing mechanisms, and the extent to which staff understand their responsibilities around sensitive information handling.
Reporting & Roadmap
A prioritised findings report covering identified gaps across access control, data protection, detection, and culture — with a remediation roadmap sequenced by risk and practical deliverability. Findings are presented in a format suitable for both technical teams and senior leadership, with clear risk ratings and recommended control improvements.
