Penetration testing in Stockholm.
Stockholm is the Nordics' fintech and SaaS capital — more tech unicorns per capita than almost anywhere on earth. That density of payment flows, customer data, and cloud infrastructure makes it a magnet for the crews who monetize access fast. We test Swedish businesses the way they actually break in.
Why Stockholm businesses call us.
Stockholm's fintech and payments ecosystem moves money at API speed — and attackers follow the money. Around it sits a deep bench of SaaS, gaming, and cleantech companies whose entire product is a cloud environment: one leaked OAuth token or over-privileged service account away from a very bad quarter. Sweden's high digital adoption also makes BEC and identity attacks unusually effective here. We hunt cloud misconfigurations, identity chains, and API weaknesses the way the intrusion crews targeting the Nordics do.
Compliance in Sweden.
Sweden's new Cybersecurity Act (Cybersäkerhetslagen, 2025:1506) entered into force 15 January 2026, implementing NIS2 with a whole-entity scope: if any part of your operations is covered, your entire organization is. It brings mandatory registration with MCF, 24-hour incident reporting, management accountability, and fines up to €10M or 2% of global turnover. Layer on GDPR (enforced by IMY) and DORA for financial entities, and regular, documented security testing is the through-line. Our reports map directly to those evidence requirements.
