In today’s threat landscape, speed isn’t optional — it’s existential. As attacks get faster, so too must your defense.
Attackers increasingly leverage automation, AI, and vast, ephemeral infrastructure to launch mass exploitation campaigns that scan, breach, and pivot within minutes — sometimes before a CVE is even publicly disclosed. Defenders, meanwhile, are often stuck pulling data manually, querying APIs, or waiting for threat feeds to update.
That’s the speed gap that attackers exploit. Today, we're launching a series of new capabilities to help defenders close that gap. These new capabilities help security teams leverage real-time threat intel to detect, block, and respond faster than ever before
The Speed Problem: Why Traditional Threat Intelligence Isn’t Fast Enough
The game has changed:
- Automation is everywhere: Bots and AI-driven tools are running scans and exploitation campaigns at machine speed.
- Exploitation is instant: Exploits are often deployed within minutes of discovery — or even before public disclosure.
- Volume is relentless: Millions of IP addresses rotate constantly in mass scanning campaigns.
Yet many defenders still operate in batch mode: querying APIs, pulling feeds manually, or reacting only after the damage is done. GreyNoise is flipping that script. We’re giving defenders real-time, automation-ready intelligence — designed to meet the speed, volume, and precision required by modern security teams.
What’s New from GreyNoise
1. Real-Time Dynamic Blocklists
Stop mass exploitation at the edge — before it gets in.
GreyNoise-verified malicious IPs involved in opportunistic reconnaissance and exploitation are delivered in real time, designed to be integrated directly into your perimeter defenses.
- Updated dynamically, second by second
- Tuned for high confidence and low false positives
- Compatible with firewalls, WAFs, and other edge devices
- Subscribe once, get live protection — no manual updates required
Use it to:
- Auto-block mass scanners and exploit attempts within seconds of detection
- Proactively protect exposed assets before CVEs are weaponized
- Harden your perimeter against “spray and pray” campaigns
2. GreyNoise Feeds
Threat intelligence that comes to you — automatically.
Say goodbye to the delays caused by polling APIs. Our new push-based data delivery means GreyNoise intelligence is streamed directly to your systems via webhooks — the moment we detect something new.
- Real-time threat indicators, no polling delay
- Zero lag between detection and delivery
- Seamless integration into existing platforms and workflows
In security, minutes (even seconds) matter. Push-based intelligence closes the speed gap between attack and defense.
3. SOAR Integrations for Response Automation
From detection to action — with zero manual steps.
GreyNoise now integrates natively with leading SOAR platforms–such as Splunk SOAR, Palo Alto Networks XSOAR, IBM QRadar SOAR–to help teams turn intelligence into action, instantly and automatically.
Automate key workflows like:
- Blocking malicious IPs without analyst intervention
- Enriching IP data during incident investigations
- Triggering alerts or playbooks when mass exploitation campaigns are detected
The result:
- Faster containment
- Consistent, repeatable response
- More time for your analysts to focus on what matters
Why This Matters
These launches are part of GreyNoise’s commitment to empowering defenders with:
- Speed: Intelligence and action in real time — because modern threats don’t wait.
- Automation: Automate your security with reliable, real-time intelligence and reduced risk of false positives.
- Integration: Delivered where you already work — firewalls, SOARs, SIEMs, and more.
- Noise Reduction: High-confidence signals only — no alert fatigue, no chasing ghosts
Who It’s For
These new capabilities are built for:
- Security operations teams seeking to automate blocking rules in near real time with reliable and actionable intelligence about IP addresses exploiting exposed vulnerabilities. Real-Time Dynamic Blocklists and SOAR integrations enable this automation use case.
- Incident responders who need to quickly understand the extent of an incident by narrowing in on the malicious network traffic that have exploited a vulnerability. Realtime updates through Feeds and SOAR integrations enable rapid responses.
- Threat intel teams looking for real-time context on emerging discovery and exploitation attempts tied to high priority risks as well as intel that enables immediate investigations to discover damages caused before vulnerability disclosures. Subscribing to web hook feeds ensures that intel teams stay updated in real time.
Modern Attacks Move Fast. Your Defense Should Too.
GreyNoise is building the future of threat intelligence for defenders who don’t have time to wait.
