If you’ve worked in security long enough, you’ve probably been burned by threat intel that looked great on paper… until it wasn’t.

Maybe it was too generic. Maybe it was stale. Or maybe it just didn’t catch the infrastructure that actually mattered—the stuff your team needed to see to act fast.

Here’s the thing: not all threat intelligence feeds are created equal.

And Guardian Intel is not just any threat intelligence feed. It is an infrastructure-based, activity-first threat intelligence feed. If you’re not using infrastructure-based threat intelligence, you’re flying blind to a massive part of the threat landscape.

What Is Infrastructure-Based Threat Intelligence?

Let’s break it down. Traditional threat intel often focuses on IOCs scraped from malware samples, phishing kits, or honeypots. You get lists of suspicious domains, hashes, or indicators that are usually already stale by the time they hit your feed.

Infrastructure-based intel, on the other hand, pulls insights from the network layer—think mail servers, DNS, IP space, and autonomous systems. It’s based on how attackers host, relay, route, and deliver their malicious activity.

In short? It’s about watching how bad actors operate rather than just collecting artifacts after they strike.

Why Infrastructure Data Gives You an Edge

Attackers can swap domains, change file hashes, or spin up new phishing kits in minutes. But infrastructure? That’s harder to fake or replace.

Here’s why that matters:

• Persistence of signal: Infrastructure elements (like open relays, misconfigured servers, or abuse-prone IPs) often stay malicious for weeks or months. They’re stickier indicators than ephemeral malware hashes or disposable domains.
• Early detection: Infrastructure activity—like botnet C2 comms, scanning, or spam delivery—often occurs before payload delivery. If you catch it early, you stop attacks upstream.
• Wider visibility: Infrastructure-based intel sees abuse across services: spam, phishing, brute force, and command-and-control. This gives you broad-spectrum detection instead of a single-silo view.
• Attack surface profiling: By watching how infrastructure is used or misused, you can map attacker behavior, not just isolated IOCs. That’s gold for threat hunting and actor attribution.

Guardian Intel: Your Source for Infrastructure-Based Intel

Guardian Intel was built from the ground up to surface this exact kind of data. Our roots are in large-scale abuse handling and abuse desk operations, so we know where the valuable signals hide—and how to extract them.

We ingest telemetry from:

• Real-time abuse complaints
• Spam traps and sensor networks
• Global email infrastructure
• DNS and IP-level behavioral data

From this, we build a unique layer of threat intelligence that isn’t found in your typical commercial feeds.

What You Actually Get

Here’s how infrastructure-based data from Guardian Intel plays out in the real world:

• You catch threats early. Like a phishing campaign starting to ramp up, before it lands in inboxes.
• You triage faster. Enrich an IP or domain with Guardian Intel data and instantly see abuse classifications, first-seen/last-seen activity, and global reputation context.
• You automate smarter. Use confidence-scored data in your SOAR playbooks to auto-block high-risk infra—without second-guessing.
• You detect what others miss. Because your feed isn’t based on commodity intel, you’ll see signals outside the mainstream radar.

The Bottom Line

Threat actors are getting faster, more evasive, and better at blending in. But they still rely on infrastructure. They still need servers to host, route, and deliver their campaigns.

That’s where you catch them. Not after the damage is done—but upstream, at the infrastructure level.

Guardian Intel gives you that upstream visibility. And when you combine it with your existing tooling—SIEM, SOAR, TIPs—you unlock a whole new level of detection, enrichment, and response.

Because in today’s world, infrastructure is the battleground. And the teams who understand that? They’re the ones who win.
