The Great Simplification: Why Leading CISOs are Shrinking Their Problem Space

In the world of 2026 cybersecurity, we are suffering from a ‘too much’ problem. Too many tools, too many logs, too many critical alerts, and frankly too many promises from vendors that more AI is the only way to solve it.

The dirty secret of the modern SOC is that more visibility often leads to less clarity. When you see everything, you can focus on nothing.

Leading CISOs are shifting their strategy. They are moving away from the Analyze Everything model and toward a concept we call Shrinking the Problem Space.

What is the “Problem Space”?

The Problem Space is the total volume of internet traffic and potential threats that your security team is forced to care about. Traditionally, organizations let 100% of the internet knock on their front door, relying on their internal”brains (SIEM, EDR, and human analysts) to sort the friends from the foes.

The result? Your most expensive human assets spend 80% of their time acting as digital janitors sweeping away the same known-bad riff-raff that should have never reached them in the first place.

Step 1: The “Digital Bouncer” Effect

Imagine a high-end club. A good bouncer doesn’t let 5,000 people crowd the foyer just so the manager can check their IDs inside. The bouncer stops the known troublemakers at the sidewalk.

threatER EnforceDNS acts as that sidewalk bouncer. By ingesting over 150 million threat indicators, it identifies and drops traffic from known malicious IPs and adversary infrastructure before it even touches your firewall.

• The Result: You aren’t just blocking threats; you are removing noise. You are shrinking the world your security stack has to “think” about

Step 2: Offloading the “Brain”

Every packet your firewall has to inspect and every log your SIEM has to ingest costs money and CPU cycles

• Firewall Efficiency: When threatER filters out the 30-50% of traffic that is objectively malicious, your firewall is suddenly faster. It has more resources to perform deep packet inspection (DPI) on the traffic that actually matters
• Analyst Sanity: When the known-bad is handled automatically, the alerts hitting your SOC are higher fidelity. Your team stops mashing buttons on false positives and starts doing actual threat hunting

Step 3: Intelligence that Actually Enforces

The integration of HYAS Protect technology into the threatER ecosystem has taken this a step further. We don’t just block domains that have attacked; we block the infrastructure that is currently being built to attack.

By identifying Indicators of Future Attack, we shrink the problem space even further, removing threats before they’ve even launched their first campaign.

The Bottom Line: Be Intentionally Exclusive

In 2026, the most secure organizations won’t be the ones with the most data. They will be the ones with the most disciplined perimeters.

Stop asking your team to find a needle in a haystack. Use threatER to burn the hay.
