01 May The security complexity trap

Why more coverage means less protection by Christo Coetzer, Director and CEO, BlueVision.

The security industry has convinced the business world that comprehensive coverage equals better protection, regardless of whether it is achieved through multiple best-of-breed vendors or one all-encompassing platform. Today, the average enterprise either deploys several security tools across their infrastructure or alternatively, they consolidate to a single vendor’s ecosystem with dozens of subscription modules. Then why is it that in the face of all this alleged protection, that breach rates continue to climb? This isn’t a paradox it’s a predictable outcome of how we’ve approached cloud security.

In a nutshell, this methodology has resulted in security teams drowning in a cacophony of alerts with each tool, or module, demanding attention, configuration and constant tuning. When your team receives 2,000 alerts daily, regardless of whether they originate from 15 vendors or 15 modules within a single platform, the real threats don’t stand out. They blend into the noise, often also referred to as white noise because they form an effective masking tool, covering up anomalous or disruptive events. But in security making the latter stand out is how we can identify the wood from the trees.

Fighting fatigue

You need to consider what actually happens in your security operations centre. Analysts swap between consoles or navigate sprawling dashboards with countless modules, each with different capabilities and alert formats. This enables critical vulnerabilities to slip through because they’re flagged by an underutilised module, or because the team is overwhelmed responding to false positives from three other capabilities they’ve licensed but barely configured. Meanwhile, attackers need only find one gap in this fragmented defence.

It’s important to understand that it is irrelevant whether you’re paying multiple vendors or adding subscription tiers to unlock features, the bottom line is the hidden cost extends beyond licensing fees. Each new capability requires integration, training and ongoing maintenance. Your security team spends more time managing subscriptions and enabling features than hunting threats. Furthermore, overlapping capabilities create blind spots at the seams, whilst duplicate alerts from poorly coordinated modules waste precious analyst hours. The cognitive load alone degrades decision-making quality when incidents occur.

Single-vendor ecosystems promise to solve the integration challenge, yet  all too often they just replicate the same problems within their own platforms. That ‘unified’ security suite still requires your team to understand which module does what, how they interact, and why you are paying for capabilities that remain dormant. The subscription model also encourages what’s referred to as ‘feature bloat’ that sees vendors continuously adding modules to justify premium tiers, regardless of whether or not organisations can effectively operationalise them.

Simplifying security

What sophisticated attackers understand and exploit to the hilt is that – unlike the businesses trying to fight them off – is that complexity is their ally, regardless of its source. They don’t need to defeat all your security tools or navigate a vendor’s entire product catalogue. They simply need to operate in the gaps between capabilities, or better yet, use your tools’ legitimate features to move laterally and utterly undetected.

The way forward is not to add yet another layer or upgrade to the next subscription tier. This is where you need to consolidate, integrate and prioritise with ruthless precision. Security effectiveness is not measured by tools deployed or modules licensed but by mean time to detect and respond to genuine threats. The companies gaining ground are not the ones with the longest vendor lists or the most comprehensive platform subscriptions, they are the businesses who have simplified their security architecture to what their teams can actually operate effectively.

Finally, ask yourself a question – can your security team articulate what each tool or subscription module protects and why? If you cannot answer this, you are not building an intense, comprehensive defence – you’re building a defence in confusion, which is decidedly not what any company wants in today’s cyber threated world.
