Threat Intelligence: How Global Attack Data Becomes Mitigation Policy

A blocklist is just the output. The real challenge in defense isn't "which IP do we block" — it's "how do we know what to block in the first place."

PacketStream Threat Intelligence analyzes attack data observed worldwide in real time to identify threats before attackers strike, and turns that data into immediately enforceable mitigation policy. This article opens up the five-stage pipeline that data travels through before a single malicious IP is blocked.

Why Static IP Lists Fall Short

Many security solutions rely on lists of "known malicious IPs." But that approach has structural limits.

• It only contains already-known threats, leaving it exposed to new attacks, reassigned IPs, and short-lived infrastructure.
• Lists with opaque sourcing and validation risk false positives that block legitimate users.
• Threats change in real time, but lists always lag behind.

What's needed isn't a "bigger list" — it's a pipeline that continuously turns data into policy.

From Data to Policy: A Five-Stage Pipeline

PacketStream refines raw traffic into enforceable policy across five stages.

Stage 1 — Collection: Seeing Attacks Flow Through Our Own Network

Our data doesn't come from a separate sensor fleet. The primary source is deep packet inspection (DPI) of all traffic passing through PacketStream's infrastructure. In other words, real production traffic itself is the first-hand vantage point — so we observe real-world attacks first, and most accurately. We inspect roughly 800 TB–1 PB of traffic every day.

Privacy first. Deep inspection operates with privacy protection as a default principle. Enterprise customers, or any customer who does not consent, can opt out at any time — and their traffic is then excluded from inspection.

On top of that, partner channels (third-party threat feeds) are combined as a secondary source. This broadens global coverage (195 countries) and cross-validates against our first-party data to further improve accuracy.

Stage 2 — Analysis & AI Curation

Collected data goes through multi-layer behavior analysis, not simple matching. Threats are judged from the behavioral patterns and context of the traffic, and AI curation filters out the noise.

Because first-party (DPI) and secondary (partner feed) data are cross-validated, we achieve a low false positive rate that a plain IP list cannot. After this stage, only verified threat signals remain.

Stage 3 — Verdict & Scoring

Refined threats are expressed in a normalized schema that applications can use directly.

• Verdict — Benign / Suspicious / Malicious / Unknown
• Score — 0 (Benign) / 1–99 (Suspicious) / 100 (Malicious) / -1 (Unknown)
• Category — threat type (e.g., Malware, Adware); multiple may be returned
• Summary — why the IP received that verdict
• RAW — raw behavior-analysis data (Advanced plan)

Stage 4 — Policy & Distribution

Verdicts and scores become enforceable policy in themselves — for example, block above a certain score, or challenge specific categories.

PacketStream distributes 70M+ threat indicators via a REST API, with data refreshed 5–50% daily to reflect the latest threats. Policy isn't a static file you build once; it's a continuously flowing stream.

Stage 5 — Enforcement: Auto-Applied to Firewalls, CDNs, and DDoS

Finally, policy is applied automatically at real defense points. Integration is just three steps.

1. Generate an API key — instantly from the console
2. Auto-block integration — automatically registered into firewall / CDN rules
3. Immediate effect — fewer alerts, reduced load

Policy built this way combines with PacketStream's Always-On inline DDoS mitigation to block attacks preemptively, before they ramp up. The result: detection up to 60 days faster than other vendors, 95%+ of large attacks blocked preemptively, and an 80% reduction in security alerts.

Why This Approach Is Different

• First-hand observation — we see attacks flow through our own network, rather than reselling purchased lists.
• Exclusivity — over 50% exclusive threat data not detected by 92 other vendors.
• Accuracy — cross-validation and AI curation keep the false positive rate low.
• Proactivity — up to 60 days faster detection blocks attacks before they start.
• Delivered reliably with a 99.9% SLA.

Closing

Knowing what to block is where defense begins. PacketStream Threat Intelligence turns real data observed on our own network into accurate mitigation policy — so you can stay a step ahead of attackers.
