Hackers at heart. Offensive security by profession.

Our history

Why we created Cyloq

Cyloq was born from a deep passion for offensive cybersecurity - and a drive to do it better. Better than yesterday and better than anyone else.

Andreas and Sam had worked together for years. Both had an early fascination with technology, not for the interfaces but the machinery underneath. How systems are built. How they break. Where the limits are, and what happens when you push past them. That curiosity to uncover what’s not meant to be found is still at the heart of everything we do.

With years of experience in both defensive and offensive security, they decided to build something of their own. A company rooted in precision, method and technical excellence. That company became Cyloq.

Our experts go after your systems with the same persistence as real attackers. We test until every path has been explored, every angle examined and every weak spot exposed. That’s how we find vulnerabilities, and help you fix them.

For us, this isn’t just a job. It’s a responsibility. A responsibility to protect the organizations that keep society running.

15+ years of hands-on cybersecurity

A partner you can trust

We bring more than 15 years of experience finding, analyzing, and fixing vulnerabilities in some of the world's most complex systems. Our team has reported critical flaws to companies like Google, Microsoft, and Apple through global bug bounty programs and holds certifications such as Offensive Security Certified Professional (OSCP).

Our work is not driven by theory, but by real-world experience from the frontlines.

We have worked with everything from tech companies and government agencies to global corporations and critical infrastructure. Over the years, we have developed a sixth sense for how real attacks unfold, how weaknesses creep in, and where the real risks hide. With deep experience in both offensive and defensive security, we know exactly how attackers think, how defenses break and how to strengthen them.

We are a partner you can trust, with the expertise and knowledge to understand your reality and adapt our work to the unique demands of your industry.

TEAMET

Idag är vi fyra personer, med massor av kompetens

Andreas Gjelset

Co-Founder & Security Consultant

Andreas är hjärnan bakom Cyloq och en av dem som faktiskt förstår systemet han attackerar, på maskinnivå. Han och Sam jobbade ihop i många år innan de grundade bolaget, och det är fortfarande den kombinationen som definierar hur Cyloq jobbar: metodiskt, tekniskt djupt och utan genvägar.

Sam Eizad

Co-Founder & Security Consultant

Innan Sam grundade Cyloq hade han redan ett cv som fick folk att lyfta på ögonbrynen, med bug bounty-träffar hos Google, Microsoft och Apple och år av erfarenhet från bolag som Certezza och Sogeti. Nu leder han det han alltid velat ha: ett litet team som gör det de stora konsultbolagen inte orkar med. Han föreläser, håller utbildningar och hackar, helst allt tre på samma vecka.

Per Idenfeldt Okuyama

Security Consultant/Penetrationstestare

Per började i rymden, bokstavligt talat. Efter år inom Security Operations på Swedish Space Corporation landade han hos Cyloq med målet att sluta nöja sig med det förväntade. Matematikbakgrunden gör att han ser mönster där andra ser kaos, vilket är precis lika användbart när man letar efter kritiska sårbarheter som när man lyssnar på vinyl (vilket han gärna gör på fritiden).

Samuel Törnqvist

Security Consultant/Penetrationstestare

Samuel simmade i svenska landslaget i nio år, och den där tävlingsinstinkten har han tagit med sig rakt in i offensiv säkerhet. För honom handlar pentestning om samma sak som simning: hitta svagheten, pressa gränsen och vinna. När han inte jagar kritiska sårbarheter hittar du honom nära vatten, fast på surfbrädan eller i dykutrustning istället.
