An increasingly challenging security landscape requires a deeper, broader, more complete approach to security – an approach where security is designed, developed and delivered as critical and integral, rather than ‘added-on’ after the fact. ‘Secure always’ isn’t just a mantra for us, it’s an imperative.”
Brennan’s early years in emergency system recovery means we understand the true cost of system outages, failures and breaches better than anyone.
That’s why we have developed a market-leading, systemised security culture and approach that makes security a fundamental in every aspect of a customer’s technology ecosystem, from design and deployment through to risk identification and rapid recovery.
We build security into the blueprint of how your whole business operates.
Brennan’s Cybersecurity Architecture doesn’t just provide superior breadth of protection. It offers the highest standards too.
With us, ISO 27001 is only one part of a multi-layered set of standards and safeguards. Brennan security experts layer local, industry, and bespoke client protocols into each customer’s security regime to give you next level confidence; the confidence of knowing we are not just managing ‘generalised’ risks, but also protecting you from the ‘actual’ risks that are more specific to you and your business.
Importantly, our hybrid, multi-layered standards are applied across our own systems, those we share with customers, and to customer-owned technologies. Brennan security means higher standards, applied to every link in the technology chain.
Malicious intent and malevolent action never sleeps and never stops. And with the work of bad actors now bolstered by the emergence of AI, the threats are becoming increasingly insidious.
The antidote? A continuous investment in tools, technology, and tactics on every front, spanning forensic, vCISO, SOC, Governance, Risk, and Compliance.
Where an MSSP will apply detection tools to detect risks, prevent incidents and spot breaches, Brennan’s broader and more sophisticated capabilities mean we go further – extending from prevention and detection to response, recovery, and ongoing improvement.
Combined with our advanced digital transformation and IT operations capabilities, this means we not only see threats sooner, but we are also able to respond to them with urgency and effectiveness. With reputations and revenue on the line, we take accountability for your security as seriously as we do our own.
At Brennan, Secure by Design means security is embedded into how your technology is planned, implemented, and operated, not bolted on after deployment. It’s supported by a secure always culture and a dedicated cybersecurity division of 300+ security experts, applying multi-layered standards across consulting, assessments, managed security, and continuous improvement.
Many Managed Security Service Providers (MSSPs) focus primarily on monitoring and alerting. Brennan combines managed security with the services that help you reduce risk upfront and uplift maturity over time, including audits, consulting, penetration testing, vulnerability management, SIEM, and a sovereign SOC, supported by a large specialist team and an operating model that spans prevention, detection, response, and recovery.
Brennan’s Secure by Design capability covers a broad range of cybersecurity services, including:
Brennan’s solutions align to recognised Australian Government and industry frameworks, including the Protective Security Policy Framework (PSPF), the Information Security Manual (ISM), and the Essential Eight. This helps organisations strengthen controls and demonstrate compliance without compromising operational outcomes. Brennan is also ISO 27001 certified and supports ISO 27001 readiness programs.
Absolutely. Brennan supports Essential Eight assessments and uplift, including prioritised action plans, measurable milestones, and practical implementation support across key controls such as MFA, privileged access, segmentation, and secure backup and restoration, so that improvements translate into real risk reduction.
Yes. Brennan provides penetration testing and vulnerability assessments, supported by ongoing vulnerability management to help identify weaknesses, validate exposure, and reduce the likelihood of compromise. Outcomes typically include clear remediation priorities so your teams can act quickly and track progress over time.
A sovereign SOC is a Security Operations Centre designed to meet data handling and operational requirements where sovereignty and compliance are critical. Brennan’s sovereign SOC, paired with SIEM and XDR, supports continuous monitoring and faster detection, especially for organisations with regulated environments or heightened risk.
An increase in the number and frequency of cyber security events was overwhelming BCE’s internal operations team and leaving the school network at a high risk of security compromise.
