Penetration Testing

Cobalt’s Pentest as a Service (PtaaS) platform, coupled with an exclusive community of testers, delivers the real-time insights you need to remediate risk quickly and innovate securely.

The FlexScore® is the result of a rigorous 2-step verification of a company’s flexibility

First we assess the flexibility options Cobalt provides and then we anonymously survey a statistically significant proportion of their employees to make sure Cobalt is as flexible as they say they are. Our assessment is based on the six key elements of flexibility: location, hours, autonomy, benefits, role modelling and work-life balance.

We ask the hard questions so you don’t have to.

What employees are saying

"Part of the reason why I joined Cobalt was the flexibility – being able to work from home, take care of my dog, run errands, and also unplug after hours was important to me, and everyone at Cobalt gets it."

About us

Cobalt was founded on the belief that penetration testing can be easier and more accessible. Penetration testing is the process of conducting an authorized, simulated cyberattack on a computer system, also known as ethical hacking.

Cobalt pioneered the Pentest as a Service (PtaaS) space by pairing a SaaS platform with an exclusive community of highly vetted testers to disrupt the old school way of testing. Today, over 1,000 customers use Cobalt to run pentests that start faster, produce stronger results, and integrate with modern development cycles.

We’re an award-winning (and fully remote) workplace with Scandinavian roots, an American base, and a global outlook. Together, we’re committed to helping agile teams remediate risk quickly and innovate securely.

Flexible working at Cobalt

Cobalt is a 100% remote-first, flexible workplace. We fully equip all Cobalters with the tools they need to do their job from home (or wherever), including a monthly stipend for WiFi and remote lunches. We have also partnered with UpFlex to provide our US and UK Cobalters with the option to work from a co-working space near them, and an optional membership at Mindspace Berlin for all Cobalters located in Germany. Even better – we're a dog friendly company!

Our working hours are flexible, and our working style is asynchronous. With Cobalters distributed across the US, Germany, and the UK (and soon to expand to more locations), we want to ensure a healthy work-life balance is maintained and Cobalters are able to focus on what matters the most to them.

We also offer excellent benefits including an unlimited holiday allowance, an attractive equity plan, and travel bonus payouts at your 2, 3, and 5 year anniversary.

Approach to diversity & inclusion

With over 45 nationalities already at Cobalt (and counting), we respect and celebrate diversity. We’re proudly committed to equal employment opportunities regardless of gender, religion, age, sexual orientation, ethnicity, disability, or place of origin. To create an inclusive environment at Cobalt, we host bi-weekly inclusion, diversity, equity, and awareness (IDEA) discussions to learn, share and support each other. We are grateful for each Cobalter's contribution to our mission — let's make security dance!

What do we think of Cobalt?

We're super excited to have Cobalt on board, a large innovative business with flexibility at its core, making penetration testing more accessible backed by their SaaS platform.

Employees informed us that they love the unlimited annual leave policy and are encouraged to utilise it. Flexibility is formed by the leadership team and it's clear that they are setting the standard with such great scores for a large business.

If you're looking to grow your career within penetration testing, then we recommend Cobalt!
