What are MSSP’S in London

Managed Security Services Provider

Managed Security Services (MSS) provide 24/7 monitoring, threat detection, incident response, policy management and continuous security improvements delivered by a dedicated security team or SOC.

Businesses choose MSSPs to reduce risk, meet compliance, and gain enterprise-grade protection without building an expensive in‑house security operation. Cybersecurity threats evolve daily, but your defences shouldn’t fall behind.

Speedster IT provides fully-managed security services that protect your organisation around the clock, combining intelligent detection, rapid response, expert analysts and proven technology to reduce risk and strengthen your cyber resilience.

As a WatchGuard Gold Partner, we offer enterprise grade protection for just £4 per user/month, making us one of the best MSSP providers in London for cost-effective, scalable security.

Whether you’re a small business in Central London or a nationwide enterprise, our MSSP services and Cyber Security Services in London are tailored to your needs.

We help you stay protected in real time from ransomware, phishing, and data breaches with cutting-edge tools and expert IT support.

Why London Businesses Need MSS Now

Cyber threats targeting UK organisations have surged in sophistication, largely due to attackers’ use of AI‑enhanced phishing, automated reconnaissance and high‑volume exploit kits.

These techniques make traditional defences and part‑time monitoring insufficient. Data shows attackers increasingly use generative AI to craft highly targeted phishing emails, scrape open‑source data at scale and automate the early stages of an attack, dramatically increasing the speed and success of breaches. 

At the same time, many companies are struggling with unfilled cybersecurity roles and shrinking security budgets, leaving them without the internal capability to run a 24/7 SOC or analyse real‑time threat data.

This combination makes a Managed Security Services Provider essential for London SMEs that need reliable monitoring, fast containment and a modern defence strategy

What’s Included in Our Managed Security Services

Our managed security service combines round‑the‑clock monitoring, proactive protection and specialist expertise to keep your business safe.

You get 24/7 threat monitoring and rapid incident response, ensuring suspicious activity is detected and contained before damage occurs. We provide managed firewall and endpoint protection (MDR) to stop malware, ransomware and unauthorised access across networks and devices.

With our SOC-as-a-Service powered by WatchGuard Security Operations Centre, advanced analytics and expert analysts watch over your systems continuously.

And as one of the top UK-based MSSP providers, you benefit from a locally‑based security team who understands the unique threat landscape facing UK businesses.

MSS vs MDR vs SOC-as-a-Service — What’s the Difference?

Understanding these terms helps you choose the right protection:

  • MSS (Managed Security Services)
    Continuous monitoring, policy management, firewall/endpoint management and alerting.

  • MDR (Managed Detection & Response)
    Threat hunting, investigation and active response — human analysts validate and contain threats.

  • SOC‑as‑a‑Service
    Full outsourced SOC capabilities including SIEM management, MDR, threat intelligence, compliance and incident response.
