Find the malware that's already talking to its attacker.
Strixl Labs spots the hidden conversations malware uses to call back to whoever planted it. The quiet traffic your existing security tools miss. Built to stop a breach before it becomes one.
The threat you can't see.
What a beacon actually is.
Malware that's already inside your network calling back to malicious attackers. Every ransomware attack, every data breach, every nation-state intrusion. They all start with a beacon nobody caught.
How long they hide.
The industry average from compromise to discovery is over six months. That's six months an attacker is inside, reading email, mapping your systems, and preparing the payout.
Why your tools miss them.
Firewalls check where traffic is going. Antivirus checks what programs are doing. Nobody is watching the pattern of conversation between two computers over time. That's where beacons live.
C2 beacons don't look like attacks.
They look like a routine check-in. A tiny message goes out, a tiny reply comes back, on a steady schedule. For weeks. Your antivirus doesn't flag it. Your security dashboard doesn't light up. It blends in with the millions of normal background conversations every computer on your network.
You only catch it if you're actively hunting for it. Strixl Labs hunts for you. Automatically, on every connection, on every upload.
From upload to verdict in three steps.
Upload your network traffic
Drop in a recording of your network activity from your firewall, your monitoring tools, or a raw packet capture. No software to install. No agents on your endpoints. If your vendor exports it, we read it.
We watch for hidden conversations
We look at every connection between two computers and ask: does this look like a real person working, or a program checking in on a schedule? We score it on timing, size, fingerprint, and whether the destination has been reported before.
Get answers, not more alerts
Suspicious connections show up ranked by severity, each with a plain-English explanation of why we flagged it. Confirm a real threat or dismiss a false alarm, and the system learns your environment.
Everything you need to stop command-and-control traffic.
Illustrative view of a flagged pair
Multi-format ingest
PCAP and PCAPNG, Zeek TSV + JSON, Suricata eve.json, NDJSON, CSV. Auto-detect with field-mapping fallback when vendors get creative.
JA3, JA4, JA4H & JA4X
TLS client, HTTP client, and X.509 certificate fingerprinting. Known-bad Cobalt Strike, Sliver, and Havoc matching plus self-signed cert flags.
Behavioral scoring
Jitter, periodicity, payload symmetry, duration stability, entropy. No signatures to chase. The engine scores behavior, not IOCs.
Threat intel built in
Emerging Threats, Feodo Tracker, VirusTotal, AbuseIPDB, IPinfo ASN, and RDAP, all merged into every flagged pair automatically.
False-positive learning
Mark one pair benign and the engine suppresses the pattern across your whole workspace. Corporate update traffic stops owning your queue.
Multi-tenant by design
Per-customer ingest streams, workspace isolation, audit log. Built for internal SOCs and MSSPs who don’t want tenant bleed-over.
See more, sooner, with what you already have.
Cut dwell time.
Find beacons in hours, not months. Shorter dwell time means less data stolen, smaller ransom demands, smaller breach-notification bill, less damage to repair.
Evidence on demand.
Every detection has a human-readable breakdown you can hand to auditors, your cyber insurer, a forensics firm, or your board. No black box.
No rip and replace.
Works with logs you already collect. No new agents, no new appliance, no new vendor to integrate. Sign up and upload a file.
