    Secure networks built for modern risk

    DDoS attacks, ransomware and advanced malware can bring operations to a standstill in minutes, and the cost goes well beyond downtime: lost revenue, regulatory exposure and lasting damage to customer trust.

    Every organisation's risk profile is different, so we don't do off-the-shelf security. We analyse your specific requirements and build protection across every level of your network, keeping threats out and operations running.

    Our network security services

    Four core services, tailored to your infrastructure and risk profile, delivered individually or as a complete protection programme.

    DDoS mitigation and prevention :

    We continuously monitor your networks for distributed denial of service (DDoS) attacks, which can grind your business to a halt if left unchecked. Careful traffic filtering and threat identification keep your high-capacity core and access networks available. 

    Close

    Next-generation firewall (NGFW) services :

    Control incoming and outgoing traffic with security policies enforced at the application, port and protocol level. We design, deploy and manage NGFW solutions, including carrier-grade platforms like the Juniper SRX series, that scale with your network.

    Close

    Incident detection and response :

    Through constant monitoring and analysis of your network, we can detect incidents fast and respond faster, providing real-time forensic information so threats are contained before they spread.

    Close

    Security verification

    Security verification:

    Your security architecture and its components should be regularly tested for weaknesses. Our Xperts assess your defences end to end, identifying gaps and prioritising fixes before attackers find them.

    Benefits of managed network security services

    Protect your network

    Take control of exactly what touches your network. Next-generation firewalls, DDoS mitigation and traffic management keep threats away from your critical infrastructure, so you're prepared for the unexpected.

    Reduce exposure to advanced malware

    Malware that infiltrates your network can spread to the systems of your customers and partners, with far-reaching reputational and financial consequences. Managed network security services dramatically reduce that risk.

    Keep it business as usual

    DDoS, ransomware and other cyber attacks can paralyse the systems your day-to-day operations depend on. Proactive monitoring and threat detection head off attacks before they land, so your teams, and your customers, never notice a thing.

    FAQs about our network security

    What is network security?

    Network security covers the technologies, policies and processes that protect your network infrastructure and the data travelling across it from unauthorised access, misuse and attack. It spans everything from firewalls and DDoS protection to threat detection, incident response and regular security testing.

    What is a DDoS attack, and how do you prevent one?

    A distributed denial of service (DDoS) attack floods your network or services with malicious traffic, overwhelming them until legitimate users can't get through. We prevent this through continuous monitoring, intelligent traffic filtering and mitigation measures that absorb attacks while keeping your services available. 

    What is a next-generation firewall (NGFW)?

    Unlike traditional firewalls, which filter traffic by port and protocol alone, next-generation firewalls add application-level inspection, intrusion prevention and threat intelligence. That means much finer control over what enters and leaves your network, and it’s scalable up to carrier-grade if you need it.

    Do you work with our existing security tools and vendors?

    Yes. As a vendor-agnostic partner, we assess what you already have, integrate with it where it works, and recommend changes only where they meaningfully improve your protection.

    How do we get started?

    It begins with a conversation and an assessment of your current security posture. From there, we recommend prioritised measures that give you the best all-round protection for your infrastructure, requirements and budget. Get in touch to find out more.
