How our holistic solutions give you peace of mind

There is no one-size-fits-all cybersecurity solution, with organisations having their own unique IT infrastructure and attacks coming from a wide range of sources. Our Cybersecurity consultants work with you across a broad range of Governance, Risk and Compliance Services (GRC) and help with roadmap development and security architecture services.

Wherever you are in your IT security journey, Brennan has developed a comprehensive range of cybersecurity services within our Security Operations Centre (SOC) that address critical areas of the IT environment – end-user training and awareness, vulnerability management, endpoint threat protection, network and perimeter security, data protection, and proactive monitoring and response that enable organisations to mitigate risks and ensure business continuity.

Our team would love to see how we can help you.

End-user Training & Awareness We’ll provide training + ensure people are who they say they are

People are our most valuable assets, yet unfortunately, they can also be one of the weakest links in an organisation’s cybersecurity controls.

We work with our customers to implement cybersecurity awareness programs that consist of education, real-world testing, and reinforcement of appropriate (and inappropriate) behaviour that can help to reduce and mitigate risks. Additionally, to ensure access to business data is planned, managed, and controlled, we centralise user identities and credentials linked to applications and systems,
ensuring organisation-wide governance.

Vulnerability Management We continually review and identify where you might be vulnerable

Our vulnerability and patch management program ensures your business data remains yours, by identifying and closing potential holes created by vulnerable software. We provide penetration testing services covering internal and external networks, wireless, application, and web-app testing, and using “black box” methodologies to simulate real attacks allows us to proactively replicate a user or authorised platform to uncover any potential risks.


Endpoint Threat Protection We’ll keep threats at bay so you can feel safe across all endpoints

Modern endpoint security platforms need to be capable of doing more than just recognising an attack – they need to analyse behaviour
and react accordingly, as well as detecting when potentially valid applications are hijacked by malware, or when a user decides to behave inappropriately.

Through Brennan’s SOC, we fully monitor and manage endpoint security services direct from industry-leading vendors, such as Sophos and CrowdStrike, including XDR and EDR, providing your organisation and people peace of mind, that someone is always watching the front and the back door.

Application Security We’ll make sure all your applications are secure

Making sure the right (approved) applications are securely running in your IT environment isn’t as easy as it seems and can take an organisations IT teams focus away from their strategic initiatives.

We help our customers select and implement the right application security tool(s) that enable audit mode deployment, and profile set up across different user groups that when enabled will block and/or alert to unwanted programs.

Network & Perimeter Security We secure your network inside and out to reduce risk

Partnering with security vendor Fortinet, we’re able to offer our customers an enterprise-grade network security stack that secures from the very edge of your network all the way down to the endpoints, which in these days of mobile and remote workforces – are often where the controls need to be strongest.

Data Protection Keeping your data secure

Our security experts start with DLP (discovery, classification, and labelling) to ensure we understand the nature and location of your data.

We ensure your organisation’s data is encrypted and monitored 24/7/365, and that robust authentication and validation systems are in place to give you peace of mind that your data remains secure and accessible by the right people at the right time.

Monitoring and Response We're always monitoring to minimise risk and disruption

Keeping a diligent watch over an organisation’s entire IT eco system 24/7/365 is critical, yet many find it difficult to achieve due to insufficient tools and systems, and resources.

More than just SIEM, Brennan’s Security Monitoring platform incorporates operational visibility, SOAR capabilities, compliance, and reporting functions – this allows us to proactively monitor your IT environment, capturing and resolving issues before they can cause disruption to your business, people, and customers.
