Why network visibility is the thread that holds cybersecurity together

Every organization is chasing the same thing in security: speed, clarity, and confidence. But in reality, most are bogged down by complexity, siloed tools, and an overwhelming flood of alerts. The latest research from Enterprise Strategy Group (ESG) illustrates this tension clearly, and the numbers tell a story every security leader can relate to.

The problem: Complexity and delay

According to ESG’s research, the most commonly cited challenge for security teams today isn’t malware or phishing. It’s complexity. Nearly two-thirds (63%) of organizations say environmental complexity is their biggest barrier to effective detection and response.

And the consequence of that complexity is time. More than half (55%) admit it takes hours, sometimes longer, just to validate if an alert is a true positive. That’s hours attackers get to move laterally, establish persistence, and blend in with normal traffic.

The common ground: The network as source of truth

So where do organizations turn when environments get too complex and alerts feel untrustworthy? To the one thing every attack must cross: the network.

Forty-one percent of security leaders say network detection and response tools are the best equipped to provide visibility across hybrid, multicloud environments. That’s because packets don’t care where they’re traveling: on-prem, across a data center, or in the cloud. They tell the whole story without bias.

Even more telling: 93% of organizations report that their SecOps and NetOps teams now share the same network visibility tools and data. In an era where silos slow response, the network has quietly become the common language of security and operations.

The turning point: Investigation over detection

Detection has been the industry obsession for years. But detection is only step one. The real battle is in investigation: understanding the scope, root cause, and impact of a threat quickly enough to act.

This is why 98% of organizations say network visibility helps with the analysis and investigation phase, with 61% calling the impact “significant.” It’s not just about spotting something suspicious. It’s about turning that suspicion into certainty so teams can move faster and with more confidence.

No wonder the top use case for network visibility, cited by 45% of organizations, is accelerating incident response processes. It’s not the alert that matters most. It’s what you can do with it.

The enabler: Continuous packet capture

The secret behind this efficiency? Continuous packet capture. Respondents to the ESG survey overwhelmingly agree that it provides more accurate detections, deeper visibility, and better collaboration between SecOps and NetOps. It means there’s always a record to go back to, always context to support an investigation, and always a single source of truth to end the “he said, she said” between tools.

The reality: Security leaders are betting big on visibility

That’s why this isn’t just theory. Nearly all organizations (91%) say they expect to increase spending on network visibility. In an era of shrinking budgets, that kind of consensus is rare. But when something makes security faster, clearer, and more collaborative, it earns its place as a priority.

Why this matters

When you pull these threads together, a picture emerges:

• Complexity is the enemy.
• Time is the cost.
• The network is the answer.
• And investigation, not just detection, is where the real impact lies.

At NETSCOUT, we believe this shift in mindset is long overdue. With Omnis Cyber Intelligence (OCI), we deliver continuous, alert-independent packet-level visibility that allows teams to unify, investigate with confidence, and reduce the time attackers have in your environment. Because in security, minutes matter, and clarity is priceless.
