— What are Managed Security Services?

What do managed security services include?

Managed security services mean outsourcing your cyber security operations to a specialist provider. Instead of relying on your IT team to detect and respond to threats — which requires 24/7 attention and deep security expertise — a Managed Security Service Provider (MSSP) handles it for you.

Coreitech's managed security service covers every layer of your cyber defence: endpoint detection and response (EDR), email security and anti-phishing, dark web and credential monitoring, firewall and network security, vulnerability management, security awareness training, and incident response — all delivered by UK-based, security-certified engineers.

Unlike point-solution vendors, we integrate all these controls into a coherent security programme with a single monthly report, a single point of contact, and a contractual 15-minute incident response SLA.

— Cyber Security Support

Ongoing cyber security support for UK businesses

Cyber threats don't stop at 5pm. Ransomware, phishing campaigns, and credential attacks happen around the clock — and the average dwell time of an attacker in a UK SME network is 197 days. By the time you notice, the damage is done.

Coreitech's cyber security support service provides continuous protection: 24/7 automated monitoring catches threats the moment they emerge; our security team triages and responds to critical alerts in real time; and monthly security reviews ensure your controls are evolving with the threat landscape.
