Frequently asked questions

A managed security service (MSS) is an outsourced security function run by a specialist provider — a Managed Security Service Provider (MSSP). It typically includes 24/7 monitoring of your IT environment for threats, management of security tools, incident response, and regular security reporting. Speedster IT provides managed security services for London SMEs.

Managed IT services keep your systems running (helpdesk, patching, monitoring). Managed security services focus specifically on protecting you from threats — active threat hunting, 24/7 SOC monitoring, incident response, and continuous security posture improvement. Many businesses need both, and Speedster IT offers these together or separately.

A SOC monitors your entire IT environment 24/7 — endpoints, email, network, cloud, and identity — using a SIEM platform that correlates events and flags suspicious activity. When a threat is detected, SOC analysts investigate, contain, and remediate. For most SMEs, using a third-party SOC is far more cost-effective than building one in-house.

Speedster IT's managed security stack includes: EDR (Endpoint Detection and Response) on all devices, email security with sandboxing, SIEM/SOAR for log correlation and automated response, dark web monitoring, DNS filtering, vulnerability scanning, and identity protection. All tools are managed by our security team — not just deployed and left.

For P1 critical incidents (active compromise or ransomware), Speedster IT's security team aims to respond within 15 minutes around the clock. Initial containment — isolating affected systems — can typically be done remotely within minutes. Full incident response, eradication, and recovery follows a documented process to minimise business impact.
