IT Security, made understandable.

Oversights happen. It’s human. Bugs, including security bugs, can’t always be prevented.

We can, however, actively search for, analyse, and resolve those bugs, before they’re abused by others.

HackDefense finds, describes, communicates, and helps you fix security weaknesses in your applications, systems and networks.

How can we help?

We aim to make our technical know-how accessible to others.

Whether you run a large bank or a small web shop: if you’re active online, the threat of being hacked is real. HackDefense tests your systems for security, assesses risks and gives you practical, understandable advice on how to approach any challenges we identify.

This is what we’re good at:

Precise Pentesting and Ethical Hacking

HackDefense tests your security thoroughly. All our consultants are professional ethical hackers with a computer science degree and OSCP/OSCE certification.

Always understandable

HackDefense reports are complete, and readable. For the board, for the CISO, and for the techs. We can support and advise you in securing your own IT infrastructure, or in designing and building secure products.

Your partner in IT security

HackDefense is more than a pentesting company. We don’t stop at a list of security issues. HackDefense actively helps you become and stay safe.

Pentesting Certificate

Starting July 1st, 2021, the new Dutch national pentesting certification has become operational. The CCV (Dutch national Centre for Crime Prevention and Safety) has set and will maintain this national standard. HackDefense has been certified and will include this mark in our security test reports. See the CCV website (Dutch) for more information.
