Offensive security isn’t a side offering, it’s our core business. On top of traditional ethical hacking, we offer premium services such as Red Team, Purple Team, IoT and OT/ICS. As a small, specialized team, we adapt faster and go further to meet your needs.
Try us once. We believe the quality of our work speaks for itself.
PolarSec started with a simple idea: companies deserve security assessments that reflect how real threats actually work.
We’re a small team with deep hands-on experience. We’ve helped companies mature their security programs, managed bug bounty platforms, and uncovered critical vulnerabilities in major systems such as industrial control systems products and major enterprise software.
Our focus is on realistic, high-quality testing. No unnecessary noise, no inflated findings — just clear, practical results tailored to your environment. Whether you’re just getting started or already have a mature security program, we meet you where you are.
At PolarSec, we believe good security comes from understanding how things can break — and helping you fix them before someone else does.
PolarSec.
Practical security from people who know how to break things.
