GreatWhiteShark Security Group is a U.S. cybersecurity contractor running continuous, internet-scale reconnaissance for sovereigns, regulated industry, and the small set of organizations who treat their attack surface like an open question.
GWSSG is registered in Albany, New York — close to the federal, state, and financial-sector clients we serve. We are independent, operator-owned, and we do not take outside capital from anyone whose interests would conflict with our clients'.
We work under contract. There is no self-serve product. There is no community tier. Engagements are scoped, signed, and staffed by the same people who deliver them — usually inside two weeks.
By federal red-team alumni and a platform engineer who'd had enough of off-the-shelf tooling.
Tier-3 data center on premises. Air-gapped analyst floor. No commodity cloud for sensitive ops.
Across cyber operations, ML research, platform engineering, and intelligence analysis.
We accept new partners only after introduction by an existing one. Privacy goes both ways.
For two decades the cybersecurity industry has trained organizations to look inward — logs, endpoints, identity, posture. That work matters, and it is not enough. The fastest growth in the threat landscape is happening on the public internet: in unindexed corners of certificate transparency, in ASN-level scanning patterns, in domains registered fifteen minutes ago, in the microeconomics of leaked credentials.
GWSSG was built on a single belief: an organization that sees the open internet the way attackers see it — continuously, relationally, at scale — cannot be surprised. Everything we do points at that thesis.
Every assertion in a GWSSG deliverable carries provenance, confidence, and a chain back to raw observation. We do not ship hand-wave intel.
Quarterly scans are theater. Our default cadence for a target's external surface is 4 hours, full-spectrum. The threat moves continuously; so do we.
The analyst who scoped your engagement is the analyst on your bridge during an incident. No tier-1 wall. No ticket queue.
We do not sell offensive capabilities, exploits, or zero-days. Our entire stack is oriented toward seeing first and getting there before the adversary does.
AI is a force multiplier when it has provenance, retrieval, and humans in the loop. We deploy models that demonstrably reduce analyst toil — nothing more.
Our scanning fleet, graph store, and ingest pipeline are deliberately unflashy. Reliability is the feature. So is determinism. So is being awake at 3 a.m.
GWSSG is a young company with a long bench. The founding team has been building variants of this system for most of a career — just inside other people's organizations.
Three founders, one rented rack, and a commitment to never build a product page before the platform actually worked.
Sentinel scanning fleet reaches 4-hour cadence with banner-grab on 800+ services. First three contracted clients onboard.
Temporal property graph store goes into production. Cross-artifact pivots in single-digit milliseconds.
Embedding-based alert collapser ships with provenance binding. Median analyst toil down 71% on covered alert classes.
Mid-double-digit clients, four continents of staff, and a continued commitment to staying small enough to actually answer the phone.
A scoped external-surface briefing is the fastest way to know whether GWSSG is the right partner.
