Insider Threat


It is no secret that Malware and Ransomware attacks are growing rapidly year-on-year, and many organisations have taken the necessary steps to protect themselves from these outside threats by installing and updating endpoint security solutions.

But what if the threat originates from inside the organisation’s network? As the attacker has access to passwords and applications and because no external threat is detected, the attack may lie undiscovered for weeks, or even months.

To defend against insider threats, organisations need to employ a combination of end-user education, endpoint security, and maintenance of applications and Operating Systems. Regimented User-defined IT policies, as well as software that monitors these should also be implemented.

ProLion’s CryptoSpike provides data transparency, by monitoring and logging user file access and identifying abnormal behaviour patterns. Should these be detected, the user’s access is blocked, and no further damage can be done.
