24 x 7 Managed Cyber Security Services & Solutions in London

​In today’s digital landscape, cyber threats are becoming increasingly sophisticated and pervasive. Attackers continuously evolve tactics, techniques, and procedures (TTPs) to bypass traditional security measures. Managed Cyber Security Services leverage cutting-edge technologies and expert analysis to effectively detect and respond to these advanced threats.

Our complete solution combines MDR-as-a-Service, ITDR-as-a-Service and SOC-as-a-Service to provide 24/7 real-time monitoring of your users, network and endpoints. This continuous visibility allows for the early detection of malicious activities and potential security incidents, minimising the dwell time of threats within your environment.

Our Security Operations Centre employs skilled cyber security professionals specialising in threat detection and incident response. These experts have the knowledge and experience to quickly assess and mitigate security incidents, reducing the impact and potential damage caused by cyber-attacks.

Which Managed Cyber Security Solution is Right for Your Business?

MANAGED CYBER SECURITY RESPONSE SERVICES

Many organisations have invested in an EDR system, such as Defender for EndPoint or Crowdstrike. Endpoint Detection and Response (EDR) is the Software that protects individual endpoints, such as workstations, servers, and mobile devices.

MDR for Endpoint devices + ITDR for Users and SOC for Infrastructure assets uses expert human security analysts to monitor your EDR Software, Microsoft 365 and Azure AD user activity and SIEM Logs to provide proactive incident response capabilities.

UNMANAGED v’s MANAGED CYBER SECURITY

MDR-as-a-Service

MDR (Managed Detection and Response) services provide a comprehensive security solution for Endpoint devices. MDR provides a combination of advanced threat detection technologies, expert analysts, and incident response capabilities.

SOC security analysts action and remediate alerts generated by EDR solutions and employ sophisticated threat intelligence and machine learning algorithms to proactively detect and respond to security incidents.

ITDR-as-a-Service

Our continuous, real-time monitoring keeps a watchful eye on your entire attack surface, scrutinizing user activities and Entra event logs to catch suspicious behaviour the moment it arises, such as:-

  • Credential Theft
  • Session Hijacking
  • Location-based Anomalies
  • Privilege Escalation
  • Malicious Inbox & Forwarding Rules

Managed SIEM

Every network device action such as Firewall logs or rule changes, is logged to a centralised SIEM solution, which stores and correlates the data. In the event of any anomalies or breaches, alerts are generated and passed on to SOC analysts for further investigation.

SOC analysts investigate potential threats, and take appropriate action to mitigate risks. A SOC primarily focuses on monitoring and responding to security events within an organisation’s network, infrastructure, user activity and behaviour.

How Does our SOC Work?

Why does it Work?

Our experts simplify the SIEM lifecycle, offering 24/7 monitoring and end-to-end management. Our Smart Filtering technology is an industry game-changer, filtering out the fluff and capturing only the data that matters. This means a more affordable approach without sacrificing security. Plus, our advanced threat intelligence and custom rules cut through the noise, revealing the real dangers.

And for compliance?

We’ve got it all—secure logs, easy searches, and regulatory mapping. With Managed Cyber Security Services, it’s everything you want from an MDR, ITDR and SIEM, and nothing you don’t.

Vulnerability Assessment v’s Penetration Testing

Imagine your organisation’s IT system is like a house. You want to ensure that your house is secure from burglars and other threats. There are two main ways to do this: Vulnerability Assessments and Penetration Testing.

Vulnerability Assessments: A House Inspection

A vulnerability assessment is akin to hiring an inspector to check your house for potential problems. The inspector will:

  • Identify Weaknesses: Look for things like broken windows, doors that don’t lock properly, weak points in the fence, and any other potential entry points.
  • Provide a Report: Give you a detailed report on all the issues found, categorising them by severity—such as minor cracks, moderate vulnerabilities, or critical risks.
  • Recommendations: Suggest repairs or improvements, like fixing the locks, reinforcing the fence, or installing better lighting.

Penetration Testing: A Simulated Break-In

Penetration testing, on the other hand, is like hiring a professional to attempt to break into your house, just like a burglar would. This professional will:

  • Attempt Real Break-Ins: Try to enter through windows, pick locks, climb fences, or find any other way to break into your house.
  • Identify Successes: Note down the points of entry they managed to exploit, how they did it, and what they could access once inside.
  • Provide a Report: Give you a detailed report on how they breached your security, the methods they used, and how you can fix these specific vulnerabilities.

In IT terms, penetration testing goes a step further than vulnerability assessments by actively exploiting the identified vulnerabilities to see if an attacker could gain unauthorised access, what data they could access, and what systems they could potentially compromise.
