The Hidden Cost of Unmanaged Alerts

Today's organisations generate far more security data than they did just a few years ago. Every endpoint, cloud application, user account and connected device produces logs and security events. While this visibility is valuable, it also creates significant operational challenges. Several factors are driving this increase.

Expanding attack surfaces

Traditional network perimeters have disappeared. Most organisations now operate across a combination of:

• Public cloud

• Private cloud

• SaaS applications

• Remote users

• Mobile devices

• On-premises infrastructure

Each environment introduces additional security events that require monitoring and analysis.

More security tools

Organisations have invested heavily in cyber security technologies over recent years.

A typical security environment may include:

• Endpoint Detection and Response (EDR)

• Security Information and Event Management (SIEM)

• Email security platforms

• Identity and access management

• Vulnerability scanners

• Cloud security tools

• Network monitoring solutions

Each tool provides valuable insight, but each also generates its own alerts. Without effective correlation, analysts may investigate multiple alerts relating to the same event, wasting valuable time and resources.

Increasingly sophisticated attacks

Attackers are also becoming more advanced. The National Cyber Security Centre (NCSC) continues to identify ransomware as one of the UK's most significant cyber threats, with criminal groups increasingly using automation, stolen credentials and legitimate administration tools to avoid detection.

Rather than launching noisy attacks, many threat actors now move quietly through environments over extended periods, making it even more important for security teams to identify meaningful indicators of compromise among thousands of routine alerts.

The challenge isn't a lack of visibility. It's knowing where to focus attention. Security alerts are designed to help organisations identify potential threats before they become security incidents.

However, when alert volumes become unmanageable, they begin to create operational and business risks of their own.

One of the biggest challenges facing security teams is alert fatigue. When analysts receive hundreds or even thousands of alerts every day, it becomes increasingly difficult to distinguish routine activity from genuine threats.

Over time, this can lead to slower investigations, inconsistent prioritisation and important alerts being overlooked. The issue isn't that analysts stop caring; it’s that humans can only process so much information before decision-making begins to suffer.

Unmanaged alerts don't just affect security teams. They create hidden costs across the wider organisation.

Time spent investigating low-value alerts reduces productivity and diverts skilled professionals away from strategic initiatives such as improving security architecture, strengthening identity management or supporting digital transformation projects.

In some organisations, security teams become trapped in a reactive cycle, spending most of their day responding to alerts rather than proactively reducing cyber risk. Over time, this increases operational costs without necessarily improving security outcomes.

Cyber security is already a demanding profession. Long hours, complex investigations and high-pressure incident response can all contribute to stress. Constant exposure to high alert volumes only adds to that pressure.

Burnout doesn't just affect individual wellbeing, it increases staff turnover, makes recruitment more difficult and results in the loss of valuable organisational knowledge.

With the cyber security skills shortage continuing to affect organisations across the UK, retaining experienced analysts has become just as important as recruiting them.

Reducing unnecessary workload helps create more sustainable security operations while allowing analysts to focus on work that delivers genuine value.

Every hour spent chasing false positives is an hour not spent improving resilience. Security leaders increasingly play a strategic role in enabling innovation, supporting cloud adoption and reducing organisational risk.

When teams become overwhelmed by alert management, these strategic initiatives often take a back seat. Effective managing cyber security means creating the capacity to prepare for tomorrow's threats.

The most effective security teams don't investigate every alert equally. Instead, they prioritise alerts based on the potential risk they pose to the organisation. This enables analysts to focus their time where it's most likely to reduce business risk, rather than becoming overwhelmed by alert volume.

A risk-based approach considers factors such as:

• The criticality of the affected system

• Whether the vulnerability is actively being exploited

• The sensitivity of the data involved

• The potential operational or financial impact

• Current threat intelligence

For example, repeated failed login attempts on a public-facing server may warrant immediate investigation, while a low-risk configuration warning on a non-production device may be addressed during routine maintenance.

Modern Security Information and Event Management (SIEM) and Extended Detection and Response (XDR) platforms help by correlating activity from multiple sources, allowing security teams to identify patterns that indicate genuine threats rather than isolated events.

Ultimately, effectively managing cyber security is about improving the quality of investigations, not simply increasing the quantity.

Automation has become an essential part of modern security operations. Rather than replacing security professionals, automation helps reduce repetitive tasks and allows analysts to spend more time investigating complex threats.

Areas where automation can add value include:

• Correlating alerts from multiple security tools

• Prioritising alerts based on severity and business context

• Enriching alerts with threat intelligence

• Automating routine investigation workflows

• Escalating high-risk incidents

• Producing security reports

Security Orchestration, Automation and Response (SOAR) platforms can also automate common response actions, such as isolating compromised endpoints or disabling user accounts until analysts have completed their investigation.

This significantly reduces response times while helping organisations manage growing alert volumes more effectively. However, automation works best alongside experienced analysts who can interpret findings, assess business impact and make informed decisions during complex incidents.

Even with the right technology and automation, many organisations lack the resources to monitor and investigate threats around the clock. This is where managed security services can provide significant value.

Rather than replacing internal IT teams, services such as a Security Operations Centre (SOC) and Managed Extended Detection and Response (MXDR) extend internal capabilities by providing continuous monitoring, specialist expertise and rapid incident response.

These services can help organisations:

• Monitor threats 24/7

• Reduce alert fatigue

• Improve threat detection

• Accelerate incident response

• Access experienced cyber security specialists

• Strengthen visibility across hybrid environments

This allows internal teams to focus on strategic initiatives while knowing their security environment is being continuously monitored. For many organisations, partnering with a managed security provider, like Celerity, is a more practical and cost-effective solution than building a fully staffed in-house SOC.

Alert fatigue often develops gradually, making it difficult to recognise until it begins affecting security performance.

Some common warning signs include:

• Analysts regularly investigating hundreds of alerts each day

• Large numbers of unresolved or ageing alerts

• High volumes of false positives

• Slow incident response times

• Limited visibility outside normal business hours

• Security teams spending more time reacting than improving security

• Growing pressure on internal security resources

If these challenges sound familiar, it may be time to review your security operations and identify opportunities to improve visibility, prioritisation and response.

Generating more alerts doesn't automatically make an organisation more secure. Without effective prioritisation, automation and continuous monitoring, increasing alert volumes can overwhelm internal teams, delay incident response and increase cyber risk.

The organisations with the strongest security operations aren't necessarily those with the most security tools. They're the ones that understand which alerts matter, respond quickly to genuine threats and continually refine their approach as their technology and threat landscape evolve.

Managing cyber security successfully means giving your teams the visibility, processes and support they need to focus on what matters most. By reducing alert fatigue and adopting a risk-led approach to security operations, organisations can improve resilience, make better use of internal resources and respond with greater confidence when incidents occur.

If your security team is spending more time managing alerts than managing risk, it may be time to rethink your approach.
