What makes Mobius Binary unique?

听

We founded Mobius Binary in January 2021 around the idea that pen testers want to hack and find vulnerabilities, not drown in timesheets and corporate process. Meanwhile, the market was racing to the bottom on price. Our view was that if you鈥檙e testing the wrong things, a cheap engagement is more expensive than a thorough one.

What makes us different is translation, I come from IT audit, risk management, and operations including managing telecommunications during the 2017 Knysna fires where 1,000 homes were lost, it was South Africa鈥檚 largest fire and it decimated communities. It taught me that technical expertise means nothing if you can鈥檛 communicate clearly with decision makers under pressure.

We鈥檙e also the firm that sometimes tells clients NOT to hire us, hear me out on this鈥� But if you are using off-the-shelf software, request the vendor鈥檚 pen test reports or attestations instead. When we do find issues, say, 100 customer credentials on the dark web, we translate it: 鈥淵our cyber insurance won鈥檛 cover this. Here鈥檚 your DORA exposure. Here鈥檚 your customer communication plan.鈥� We鈥檙e Crest-accredited for technical rigour, but we speak business risk, not CVE scores.

What鈥檚 your advice to aspiring entrepreneurs?

听

Start by solving a problem you actually understand deeply. Mobius Binary exists because I watched brilliant pen testers drowning in corporate process whilst trying to translate security findings into executive language. I live(d) both problems.

Second: build with a clear cultural thesis. If your culture is 鈥渨e鈥檙e professional and work hard,鈥� you have no culture, that鈥檚 table stakes. We created a company where security professionals could focus on technical excellence, not bureaucracy.

Third: be willing to say no to revenue. We regularly tell clients not to hire us for certain tests. That honesty builds more trust than maximising every opportunity.

Finally: find partners who complement your weaknesses. Rob Len, our Technical Head, brings pure hacking expertise whereas I bring business risk translation. Founding teams that are too similar create blind spots that are often the end of companies.

What excites you about Mobius Binary?

听

The timing. Security is finally becoming a boardroom issue, but most organisations haven鈥檛 figured out the operational side yet.

For example: we worked with a global company with operating locations in almost every country. One of our threat assessments found thousands of unauthorised Facebook pages. IT couldn鈥檛 determine which were legitimate versus scams. Marketing wasn鈥檛 involved and couldn鈥檛 approve takedowns. HR had no protocol for credential breaches. It鈥檚 sort of the perfect paralysis in this world.

That鈥檚 the opportunity. Security isn鈥檛 just IT鈥檚 problem, it鈥檚 marketing鈥檚 when brand impersonation dilutes campaigns, HR鈥檚 when remote workers use compromised credentials, legal鈥檚 when suppliers are breached.

And we can鈥檛 ignore the fact that the technology has transformed. Five years ago, dark web monitoring was expensive and difficult. Today we scan for exposures in near real-time. We鈥檝e gone from 鈥測ou鈥檝e been breached, here鈥檚 your response plan鈥� to 鈥渉ere鈥檚 what鈥檚 exposed right now, let鈥檚 fix it before the breach can happen.鈥�

听

How has Mobius Binary evolved in recent years?

听

The biggest shift is from pure pen testing to cyber threat intelligence and continuous monitoring. We kept hearing 鈥淭his report is perfect, but by the time I get budget approval, what鈥檚 changed?鈥�

That led us to dark web monitoring, breach database analysis, supply chain risk assessment, understanding what adversaries already know before they attack. It鈥檚 the difference between testing your locks versus discovering someone鈥檚 been mapping your building for months.

We鈥檝e also evolved how we communicate, penetration testing reports are usually technical, they are CVSS scores, remediation steps etc. We鈥檝e learnt into structuring our reports around business impact first: regulatory exposure, and what needs fixing this week versus next quarter. This doesn鈥檛 mean that technical takes a back seat, it is still what we do, but we realised that a focus that allows management to know what is going on, and what needs to be done, what the risks are etc, means we can do the technical AND provide companywide understanding.

What can we expect from Mobius Binary in the future?

听

The immediate focus is establishing credibility in the UK in the way we have done in RSA, strong credibility through thought leadership, speaking engagements, and sector-specific expertise and in the end, drive business growth. We鈥檙e developing tailored cyber threat intelligence, what matters to wealth management versus manufacturing versus fintechs.

AI governance is becoming a major business imperative/challenge, and I don鈥檛 mean AI-powered tools, but helping organisations understand security implications. What happens when Copilot surfaces restricted SharePoint docs? How do you govern AI in regulated environments?

The cross-functional opportunity excites me. Marketing needs dark web monitoring for brand impersonation. HR needs credential breach monitoring. Legal needs supply chain visibility. The tools exist in IT, but nobody鈥檚 built operational frameworks to make it work.

We鈥檙e exploring strategic partnerships with M&A advisors for pre-deal security due diligence, business consultancies for market entry planning, family offices for cyber as a client service differentiator.

Longer term: changing how organisations budget for security. From reactive (鈥渟omething broke, panic spend鈥�) to proactive business cases: 鈥淗ere鈥檚 your current exposure, here鈥檚 exploitation cost, here鈥檚 prevention cost.鈥�

The next chapter isn鈥檛 about becoming the biggest firm. It鈥檚 about being the firm that changes how organisations think about security, from compliance checkbox to strategic advantage.
