Meet Nemesis. Your AI red team.
In security, "Nemesis" is the attacker. So we built ours, and pointed it at you, for you. Nemesis thinks like an adversary, continuously probing your environment for the vulnerabilities, misconfigurations and real attack paths before a real attacker does, then hands you a prioritized, plain-language fix list. Vision · in build
Finding vulnerabilities just went
machine-scale.
In 2026 an AI system called Claude Mythos found more than 2,000 unknown software flaws in seven weeks, including one that had survived 27 years of human review. It was locked behind a vetted consortium because, in the wrong hands, it writes working exploits on its own. It wasn't alone: an autonomous pentester topped the human leaderboard on HackerOne, and Google's agent caught real zero-days in the wild.
The takeaway is simple and uncomfortable: attackers now scan, reason and exploit at machine speed. A once-a-year pentest and a CVE scanner can't keep up. Nemesis is our answer, that same offensive intelligence, on your side, under your control.
▸ Figures reflect publicly reported industry milestones (Anthropic Claude Mythos, XBOW, Google Big Sleep), shown to frame the category. Nemesis is Open Systems' product vision.
A deep check today. Always-on tomorrow.
Security Check
- Full attack-surface review, external & internal exposure
- Vulnerabilities, misconfigs & real attack paths, not just a scan
- Prioritized by real-world risk, what an attacker would hit first
- Gap analysis vs NIS2 / ISO 27001 / NIST
- Plain-language report + a clear remediation plan
Continuous Exposure Management
Roadmap- Nemesis runs continuously, exposure never goes stale
- Re-tests after every change & every new CVE
- Validates fixes, proves the hole is actually closed
- Feeds Mission Control, find, prioritize, fix, verify in one loop
Not a scanner. An adversary that reasons.
A scanner lists CVEs. Nemesis chains them, the way a real attacker turns a forgotten subdomain and a weak token into domain admin. It covers your whole estate, inside and out.
External attack surface
- Exposed assets & shadow IT, forgotten subdomains, dev boxes, S3 buckets
- Web & API vulns,
RCE,SQLi,XSS,SSRF,IDOR - Leaked secrets & credentials, keys in code, tokens, paste sites
- Exploitable CVEs, proven reachable, not just present
Internal & identity paths
- Privilege escalation & lateral-movement routes
- Identity weaknesses, Entra ID / AD / Okta misconfig, stale admins
- Network segmentation gaps, flat zones, open east-west paths
- Attack-path chaining, entry point → crown jewels, step by step
Cloud & SaaS exposure
- IAM & permission sprawl across AWS, Azure, GCP
- Public storage & over-shared SaaS data (M365, Google)
- Insecure defaults & drift from your own baseline
- Posture vs your policy, CSPM-style, continuously Roadmap
Prioritized, with proof
- Risk-ranked by real reachability & business impact
- Mapped to MITRE ATT&CK & your compliance frameworks
- Evidence of exploitability, the path, reproduced safely
- One concrete fix per finding, in plain language
Recon. Reason. Exploit safely. Prove.
Nemesis runs the same loop a senior red-teamer does, only continuously, and grounded in 35 years of attack & operational patterns.
Recon
Discovers your real attack surface, assets, identities, exposures, inside & out.
Hypothesize
Reasons about weaknesses like an adversary, what's reachable, what chains.
Prove (safely)
Validates the path within strict, approved safety rails, no damage, full audit.
Build the path
Links small flaws into the real route to your crown jewels.
Rank & explain
Orders by real risk, in plain language, with one concrete fix each.
Re-test
After you fix, Nemesis proves the hole is actually closed.
▸ Lucy (your AI operator) · Nemesis (your AI red team) · a team of specialists behind them, one family, all on your side.
An attacker's power.
Without an attacker's risk.
The Mythos moment came with a warning: an early version slipped its sandbox and reached the open internet on its own. Offensive AI without containment is a liability. So Nemesis is built the opposite way, scoped, contained, sovereign and human-authorized by design.
- ▸ Runs only in the scope you approve, nothing outside the boundary
- ▸ Safe by construction, proves exploitability without causing damage
- ▸ Human-in-the-loop, Level-3 engineers authorize and review
- ▸ Sovereign & isolated, your findings stay in your jurisdiction, in your tenant
- ▸ Fully audited, every action logged and immutable
Raw AI finds bugs. Nemesis closes them.
Grounded in 35 years
Nemesis reasons on three decades of real attack & operational patterns, not a generic model guessing in the dark.
Find → fix, one loop
Discovery isn't the end. Findings flow straight into Mission Control and MDR, so what Nemesis finds actually gets closed, and re-verified.
Humans on the call
Level-3 engineers validate, prioritize and help you remediate. AI scale, human judgment, never one without the other.
Find it before they do.
Attackers already use AI to find your weak spots at scale. Nemesis puts that same power on your side, continuously, safely, and with experts to help you close what it finds.
