Enterprise defenses are stronger than ever at the edge, but new data from Picus Labs shows internal defenses collapsing. Learn how quiet, silent attacks are winning and what you can do to close the gap.
Enterprise defenses are built to catch the attacks that make noise. The alarm bells, the flashing dashboards, the obvious brute-force attempts. But this year's data tells a different story: attackers are winning by making none at all.
According to Picus Labs' new Blue Report 2026, which analyzed more than 338 million real attack simulations across actual client production environments in the first half of 2026, defenses are having one of their strongest years yet. Average prevention effectiveness is up across the board. And yet, the report reveals a troubling gap that's becoming impossible to ignore.
### The Edge Is Holding, But the Inside Is Wide Open
Here's the headline: perimeter defenses are doing their job. Firewalls, intrusion prevention systems, and email gateways are blocking more threats than ever before. The edge of the network has never been stronger. That's the good news.
The bad news? The inside is a different story entirely.
Picus found that while prevention at the edge improved significantly, internal defenses collapsed in the same period. Think of it like a fortress with impenetrable walls but no guards inside the courtyard. An attacker who gets past the front gate essentially has free rein.
- Edge prevention effectiveness: up significantly year-over-year
- Internal network prevention: down, creating a dangerous blind spot
- Detection gaps: attackers are exploiting the space between perimeter tools and internal monitoring
### Why Quiet Attacks Are Winning
The most successful attacks in 2026 share a common trait: they're silent. They don't trigger alarms because they don't look like attacks at all. They use legitimate credentials, move laterally at slow speeds, and blend in with normal network traffic.
This is where antidetect browsers come into play. These tools, which allow users to mask their digital fingerprints and appear as entirely different devices or users, are becoming a critical piece of the attacker's toolkit. But here's the thing: they're also becoming essential for defenders.
If you're not using an antidetect browser as part of your security strategy, you're fighting with one hand tied behind your back. The best antidetect browser solutions let security teams simulate real user behavior, test their own defenses, and identify the silent attack paths before the bad guys do.
### The Numbers Don't Lie
The Picus report is based on real-world data, not theoretical models. Over 338 million attack simulations were run across production environments, meaning these are the actual attack paths that threat actors would use. The findings are sobering:
- Attackers are increasingly bypassing perimeter controls using valid credentials
- Internal segmentation is failing, allowing lateral movement in under 10 minutes
- Detection rates for stealthy attacks dropped by nearly a quarter compared to the previous year
### What This Means for Your Security Posture
If your organization is relying on edge defenses alone, you're leaving the front door locked but the windows wide open. The data is clear: you need to focus on internal visibility, detection, and response.
Here are three practical steps you can take today:
1. **Test your internal defenses** using attack simulations that mimic quiet, low-and-slow techniques. Don't just run loud, obvious attack scenarios.
2. **Deploy antidetect browser technology** for your security team. It lets you see your network the way attackers do, from the outside in, with realistic digital fingerprints.
3. **Monitor for credential abuse** rather than just malware signatures. The quiet attacks are almost always identity-based.
### The Bottom Line
The fortress walls are holding, but the treasure room is unprotected. Attackers have figured this out, and they're changing their tactics accordingly. The best antidetect browser solutions aren't just for the bad guys anymore — they're a critical defense tool.
The data from Picus Labs is a wake-up call. Edge defenses had their strongest year yet, and yet breaches are still happening. The difference is that the successful attacks are the ones you can't hear coming. It's time to start listening for silence.
If you're serious about closing this gap, start by evaluating your internal detection capabilities and consider adding antidetect browser technology to your security stack. The quiet attacks are coming. Make sure you're ready for them.
