In today’s ever-evolving digital landscape cyber threats are becoming increasingly sophisticated, leaving organisations vulnerable to data breaches, unauthorised access, and potential financial losses. As a business leader, it’s crucial to ask yourself: Are you confident in your security posture? Are you equipped to detect and respond to cyber threats effectively? Would you recover and what would be the impact to your business if you were breached?

A Security Information and Event Management (SIEM) solution is a comprehensive and sophisticated cybersecurity tool designed to enhance an organisation's ability to detect, monitor, and respond to potential security threats and incidents in real-time. SIEM integrates various cyber security technologies, including log management, event correlation, and threat intelligence, into one centralised platform, so that it can identify unusual patterns, anomalies, and suspicious activities that may indicate security breaches or attacks. This generates actionable alerts and reports for security teams to quickly investigate and mitigate any potential threats.

Understanding SIEM is crucial for anyone concerned about the security and continuity of their digital assets. SIEM tools play a critical role in enhancing an organisation's cybersecurity posture, enabling them to proactively detect and defend against cyber threats and preventing potential data breaches and disruption to critical operations.

As a standalone service, SIEM solutions can enhance threat detection and response capabilities. However a managed service can truly unleash the potential of cyber security investments. Lets take a deeper dive into why.

Why you should consider switching to a Managed SIEM Service

The role of SIEM

Cyber attacks are evolving; driven by the rapid advancement of technology, changing threat landscapes, and the evolving strategies of malicious actors. As organisations adopt new technologies, the increasing reliance on digital solutions across various industries provides a larger attack surface for cybercriminals to exploit. Criminals are constantly finding innovative ways to target and exploit new vulnerabilities.

A SIEM solution is like an alarm. It gathers data from multiple sources within the IT environment, including logs, events, and other security-related information. It then aggregates and correlates this data, in order to identify patterns, anomalies, and potential security incidents within its network. If suspicious or malicious activity is detected it generates alerts, sent to the security operations center (SOC) or the responsible security personnel for investigation and appropriate action.

SIEM is an indispensible tool for security teams, providing unparalleled visibility into an organisation’s IT infrastructure. With a comprehensive view of security incidents in real-time and the ability to filter out unrelated events, IT teams can identify and focus on genuine cyber threats, enabling faster incident response and minimising downtime. SIEM solutions do more than just detect and respond to known threats; they actively contribute to threat intelligence and incident analysis. SIEM solutions enhance an organisation's ability to detect emerging threats and proactively adapt their defences.

Why use a managed service?

Utilising a managed SIEM service can be an incredibly powerful way to extract maximum value from security investments, providing a more cost efficient approach to managing cyber security needs. An in-house SIEM solution requires substantial investments in hardware, software, licensing, and skilled personnel to implement and maintain. Instead, managed services allow organisations to pay for the services they need without the burden of upfront costs, ongoing maintenance expenses, and high salaries. Managed services also accommodate for organisational change, and any resulting increase or decrease in cyber security needs. Easy to scale up or down to accommodate any fluctuations in demand, Managed SIEM ensures that there is no reduction in the strength of a business’ security infrastructure through periods of change.

SIEM is a cyber security resource, and so managing this solution in-house requires specialised skills and expertise – many organisations lack a dedicated team, and even more are struggling to recruit for it. Outsourcing cyber security solutions, such as SIEM, provides access to teams of experienced, skilled security professionals who are well versed in up-to-date threat detection and prevention methodologies. Typical managed services also offer 24/7 support – cyber security events can happen at any time, and continuous monitoring ensures that any threat receives an immediate response.

Alongside top-standard security teams, organisations that leverage manage SIEM solutions also gain access to the latest tech. Managed SIEM service providers keep their systems up-to-date with the latest threat intelligence, security patches, and technology advancements; ultimately providing even more fortification, and bang for buck, of a business’ cyber defences.

A Layered Approach to Cyber Security

Celerity takes this one step further with a layered approach to its Managed Cyber Security Services. From Endpoint Detection to Incident Response, Celerity’s team of accredited security experts can support an organisation's entire security strategy, improving its cyber posture, advancing its maturity, and supporting its recovery.

SIEM is one critical part of an overall security strategy. Many organisations manage each aspect of their security environment separately, with each area employing a different tool or application to achieve its goal.  This will, to some extent, protect a business’ infrastructure. However, it is also incredibly inefficient and does not enable IT teams to extract maximum value from security investments.

Using standalone applications for security operations only silos off information. Instead, a consolidated approach to security enables streamlined processes and communication. An organisation’s SIEM solution, for example, can share its threat intelligence and analysis with all other security applications, which only enhances detection and response capabilities.

Increased visibility and correlation of events across the entire system makes it far easier to identify any irregular patterns and potential threats. This consolidation facilitates accurate, comprehensive, and fast threat detection.
