About SharpSec
Founded in 2012. Advanced penetration testing, dedicated security research, and custom security tooling.
What We Do
Our principle is simple: security should be a business enabler, not an obstacle.
As creators, not just consultants, we develop security software including Portspoof Pro and NightWatchDog ASM, alongside custom tools built for unique client challenges.
We scope each engagement to the target and bring in the specialists it needs, with findings we prove, prioritise, and retest.
