CYBER SECURITY
Quality services for organisations of every size
Thread Led Penetration Τesting (TLPT)
An advanced and targeted form of Penetration Testing. Unlike the traditional approach TLPT is based on real-world attack scenarios and current threat intelligence, in order to simulate as much as possible an actual cyber-attack. A more focused approach that yields better results.
Red Teaming
The ultimate test of your security walls. A combination of physical and digital intrusion against your organisation meticulously built security measures. An actual real-world engagement that will determine if you are secure or not.
NIS2 Compliance
NIS2 introduces a set of cybersecurity requirements for organisations within the EU.
In other words, that’s the cost of doing business within the block. We can help you reach those requirements efficiently and with the minimum effort from your side.
