True security for true confidence 

For almost three decades, Brennan has been at the vanguard of cybersecurity. We started life helping companies recover from IT disasters, but as cybercrime grows ever more sophisticated, we’ve responded by developing a proactive digital-defence ecosystem that delivers true protection for your business.

With millions of dollars, customer relationships and your reputation at stake, we believe true security demands protection that is as continuous, comprehensive and uncompromising as the risks we all face.

Peter Soulsby
Head of Cyber Security

We live in a world where risk is on the rise; not just from criminal activity, but from increased complexity; continuous technology change; stricter compliance and governance requirements; as well as the realities of day-to-day human error. That’s why we believe true security is always proactive, always testing and probing, and never takes a break. We aim for the most comprehensive and complete approach to security because we know what’s at stake.”

Brennan Experience

Battle-ready solutions.
Rock-solid support.

Brennan offers a full suite of cybersecurity services from consultancy to implementation and ongoing management. 

Brennan’s formidable array of resources and systems watches over your organisation’s entire IT ecosystem 24/7/365. Our capacity to detect threats allows us to capture, respond to and resolve issues before they cause disruption to your business, employees or customers.

More than just SIEM, Brennan’s Security Monitoring platform incorporates operational visibility, SOAR capabilities, compliance, and reporting functions for true visibility.

Built on a decades-deep foundation of front-line experience tackling risk assessments, security architecture design and compliance frameworks, Brennan’s advisory services lead the industry in delivering tangible, executable strategies that enhance your organisations’ security posture.

As external threats grow, so does external scrutiny. That’s why Brennan’s vCISO and GRC services are here to guide and advise on the framework and processes needed to ensure your operations align with industry regulations, maintain governance standards, and manage risks effectively.

It’s not if things go wrong. It’s when. We know that cybersecurity incidents happen. And we know what it takes to recover from them. Our team of incident responders work hand-in-hand with our major incident management teams to respond to cybersecurity incidents and help get your business up and running in the shortest possible timeframe.

With Brennan, your organisation’s data is encrypted and monitored 24/7/365, with robust authentication and validation systems that give you peace of mind that your data and intellectual property is only accessible by the right people at the right time.

Offence is the best form of defence, and Brennan’s offensive security services - including comprehensive and intensive penetration testing and red teaming - is designed to do exactly that. By pressure testing your digital infrastructure, our systems can identify chinks in your cybersecurity armour and advise where and how you can bolster your digital-defence posture.

Making sure the right (approved) applications are securely running in your IT environment can divert your IT team’s focus from their real priorities. We help our customers select and implement relevant application security tools to alert us to and block unwanted programs.

The Brennan vulnerability-management regime proactively manages potential weaknesses in your system. Our vulnerability and patch management program identifies and closes potential holes created by vulnerable software. And our penetration testing services, and simulated attacks help us surface issues across internal and external networks, wireless, application, and web-apps for true confidence.

Brennan endpoint security platforms don’t just recognise attacks and dangerous user behaviour – they automatically analyse and react to the events to quickly safe-guard your business. 

Brennan’s SOC monitors and manages endpoint security services direct from industry-leading vendors, such as Sophos and CrowdStrike, including XDR and EDR, providing true peace of mind that someone is always watching both the front and back door. 

Brennan’s cybersecurity awareness programs play a vital role in managing human risk factors. Our programs include education, real-world testing, reinforcement of positive behaviours and minimization of negative ones.

We also ensure access to business data is planned, managed, and controlled, centralising user identities and credentials linked to ensure true organisation-wide governance.

Partnering with leading network security vendors, we offer an enterprise-grade network security stack that secures everything from the edges of your network to its endpoints. So you are genuinely secure from the inside, out. 

Navigating the risk journey together

Cybersecurity isn’t a solo pursuit. It’s a joint responsibility. Which is why we immerse ourselves in your business and technology, ensuring we fully understand the what’s and the why’s keeping you awake at night.

We then take a pragmatic and practical approach to buy down those risks to a defensible level, using a modular approach and tailoring solutions that contour to your unique risk landscape.

With seasoned cyber experts, cogent methodologies, and a track record of helping businesses – from pre-emptive planning all the way through to ‘when it happens’ – we’re here to walk your risk journey with you.

A security mindset, baked-in

Brennan’s cybersecurity services and solutions don’t operate as standalone siloes. They’re tightly meshed company wide. Our advanced Security Operations Centre, supported by Advisory, Offensive Security, Incident Response and Engineering, work hand-in-glove with our Managed IT and Digital businesses to offer full-spectrum protection.

From chasing down threat actors and protecting your assets 24/7/365, through to reporting to your Board and advising on your strategy, the full might of Brennan is at the ready to deliver, whatever the threats might be, whenever they might emerge.
