It is often said that an adversary needs to get lucky only once, yet a defender must be lucky every time

At Lab539, we don’t believe this has to be the case

We created Lab539 to help organisations protect what really matters by turning the tables on this dynamic.

We do this by using an approach we call Tailored Cyber Defence Operations (TCDO). TCDO is a proven and effective way to defend against cyber threats. Devised by Lab539, it works in conjunction with and enhances existing cyber security investments to protect core functions.

If you're looking for a way to turn the tables on adversaries and protect what really matters to your organisation, then contact us.

  • Whether to prevent business disruption or mass loss of life it starts by understanding the environment, how it could be attacked and why

  • Just because something is legacy and unsupported, if it is important it still deserves protection. Whether legacy, based upon a closed technology, or you simply have no desire to work with the vendor, it can still be made resilient.

  • We have a legacy of securing technologies that other security solutions do not go near or understand. We’re not about mass market, we’re focused on you and what matters to you.

At Lab539 we look at the problem differently. We start at the end and work backwards.

Our focus is not in preventing an adversary during their positioning phase, but in preventing an adversary carrying out their actions on objective - the thing that would result in catastrophic consequences.

We’re not about collecting alerts, ingesting terabytes of data to sift through or charging you to eliminate the false positives we created. We’re about building real resilience, empowering environments to defend themselves by bringing context into the equation in the way only a human can.

We believe that traditional cyber security approaches are essential, but they have limitations. If you feel you’re fighting an uphill battle uplifting your cyber security, it’s probably because you’ve already found those limitations.

At Lab539 we start at the end because it is extremely effective and means we don’t have to continually play catch-up.

Lab539 is proud to be part of CYBERUK 2024

Join us on Tuesday 14th in the Technical Masterclass where we’ll talk about Securing Downstream Oil from cyber threats as part of the Modern Approaches to Securing Operational technology topic area.

We also have a stand (stand K4), which is on Level 5, Hall 4, near to the NCSC stand. Do pop by and meet the team, talk OT security, tailored cyber defence or anything else that takes your fancy.


Tailored Cyber Defence Operations

TCDO is extremely effective in securing critical functions and workloads and can be applied to any environment.

Here are some examples:

Operational technology, industrial and control system environments

As control system environments become increasingly connected applying layers of security becomes necessary.

Generic controls are not sufficient for most environments, they lack context and environmental understanding. TCDO starts with the context so that defences are tailored, appropriate and effective without disruption.

Post incident resilience

Should an incident occur your attack surface may change radically.

TCDO cuts through the noise and focuses on the actual and current attack surface and tailors defences to that, utilising your attack surface to your defensive advantage and ensuring that defences are appropriate to your actual current attack surface.

New and emerging technologies

New and emerging technologies don’t have “signatures” for attacks, weaknesses may be undiscovered and the substance of the threat an unknown.

TCDO enables technology and processes to defend themselves against the attacks which they will face by understanding what those attacks may be, how they may manifest themselves.

Legacy technologies

Just because you rely on a legacy or unsupported technology doesn’t mean you need to sacrifice on security. At Lab539 we know that any technology can be secured, it just requires context.

TCDO starts with that context and enables legacy technologies, and technologies with known and unknown security flaws to be secured and made resilient, usually in ways the OEM could never achieve.
