Pentesting has moved to Glippen

Until August 2026 I offered free pentests here on erik.no to build a portfolio. That period is over. Pentesting, domain security checks and Microsoft 365/Azure access reviews are now delivered as a paid service through Glippen, with fixed, published prices. It's still me doing the work.

The Glippen site is in Norwegian. English-speaking clients are welcome – use the contact page and I'll take it from there.

The blog stays here. Read the pentest write-ups from earlier engagements.

What clients say

Translated from Norwegian.

  • Wiktor, AutoHobby AS
    Carried out a security test of our website and found a vulnerable point we weren't aware of. The hole was patched quickly, and we got a clear explanation of what was wrong and how it was fixed.
  • Web designer (wishes to remain anonymous)Read the full story (Norwegian) →
    As a web designer, the security of the sites I build is something I genuinely take seriously. So I was very surprised and alarmed when Erik discovered that my own website was an easy target for spoofing. I'm incredibly grateful to have been made aware of this so I can do something about the flaw, and I'd strongly recommend other businesses get their websites checked too.
  • Greg, ReAI AS
    Erik has helped increase security at ReAI, which means an incredible amount to us as a provider of accounting software.
  • Client (wishes to remain anonymous)
    Erik tested our systems and found holes we weren't aware of. With his help, we were able to effectively close these before any potential 'black hats' could help themselves to sensitive data.
