The finished product

AegisAI beside SentinelOne Singularity.

SentinelOne is among the strongest endpoint platforms on the market. The first two rows are mostly equivalent: both detect on the device, both keep protecting offline, and both roll ransomware damage back from shadow copies. On every other row AegisAI is ahead: where an incident is understood, who it is explained to, how the product learns, and what it costs to own.

Cloud-centred platform

  1. Analyst console — people investigate and decide
  2. Vendor platform, usually its cloud — data lake, correlation, threat hunting, generative assistant
  3. Endpoint agent — on-device detection and enforcement

Much of the understanding happens away from the machine.

AegisAI

  1. Plain-English incident, for the person at the machine
  2. Graduated response, rollback, signed forensic archive
  3. Triage Llama 3.2 3B + deep Llama 3.1 8B, fine-tuned by AegisAI and by you
  4. Rules, signatures, edge AI, sub-100 ms
  5. Signed, chained telemetry and WFP enforcement

Nothing leaves the box — and nothing needs to.

Today's leaders were built around a vendor platform. Their generative assistants help analysts investigate after the fact. The person at the affected machine gets an alert, not an explanation. Response is largely kill, quarantine or isolate, with shadow-copy rollback in the best of them. Their models are tuned centrally, on data pooled from all customers, so they learn the average customer rather than your machine. Their cost scales per endpoint, every year, to fund the pipeline behind them.

SentinelOne SingularityAegisAI — the finished product
On-device detectionMostly EquivalentStatic and behavioural AI engines on the agent. Keeps protecting offline.Sigma rules, YARA, signatures and four edge models on the device. Keeps protecting offline.
Ransomware recoveryMostly EquivalentRollback from Windows shadow copies, including registry keys and scheduled tasks.Surgical rollback from shadow copies and a signed change journal, files and registry.
Incident explanationAegisAI is better: the explanation is written on the machine for its owner. SentinelOne’s assistant helps an analyst in the vendor console.Purple AI: a generative assistant for analysts investigating in the SentinelOne console.Every incident explained automatically, on the endpoint, by two fine-tuned local Llama models — for the person at the machine, with no console or analyst required.
Where the AI reasoning runsAegisAI is better: both models stay on the endpoint, so air-gap is the default rather than a separate edition.Detection on the agent. Correlation, hunting and Purple AI on the SentinelOne platform — cloud by default, with on-premise editions for regulated and air-gapped sites.All of it on the endpoint, both language models included. Air-gapped operation is the default, not an edition.
Detection contentAegisAI is better: the rules are open and auditable, and each author’s name travels with the verdict.Proprietary engines and models.Open, auditable content — SigmaHQ rules with their authors credited, YARA and ClamAV — beside the local models, plus the customer’s own rules and signatures.
ResponseAegisAI is better: it takes the least destructive step that fits, and a low-confidence verdict cannot destroy anything.Kill, quarantine, remediate, network quarantine and rollback, per policy.A four-rung ladder chosen by a confidence-and-severity router. Low confidence never destroys anything, and every action seals a signed evidence archive.
Evidence integrityAegisAI is better: the record is signed and hash-chained as it is collected, not only shielded from tampering afterwards.Anti-tamper protection of the agent.Telemetry Ed25519-signed and hash-chained at the source. Sealed, signed .aegis forensic archives.
LearningAegisAI is better: it adapts to this machine, not to the average customer, and the owner fine-tunes it on their own policy and incidents.Models trained and updated centrally by the vendor.Per-machine LoRA adapters from signed specialist feedback, shadow-evaluated against a frozen golden model — and fine-tuning by the owner, on the owner’s own policy and incidents.
Value and ownershipAegisAI is better: no cloud pipeline to fund. Updates sit beside what the customer owns and never overwrite its own rules or remove its own fine-tuning.Per-endpoint annual subscription, in tiers.A perpetual licence, no compulsory retainer; an optional retainer from USD 5 per machine per month for new rules, definitions, signatures and fine-tuned models.

What the market charges today

List or reported prices per endpoint, before the generative-AI layer where that is sold separately. For 100 endpoints over three years, SentinelOne Singularity Complete at list price comes to $53,997 and CrowdStrike Falcon Enterprise to $55,497, and that bill repeats for as long as the subscription runs. AegisAI’s optional retainer for the same 100 machines, at USD 5 per machine per month, comes to $18,000 over three years — and protection continues without it.

The market today: who comes closest

We surveyed the leading AI-driven endpoint platforms and the open, self-hosted alternatives in November 2026. Several run machine learning on the endpoint for detection. Several offer a generative assistant. A few can be self-hosted with a local language model on a server. None runs language-model reasoning on the protected machine itself, explains each incident to that machine’s owner, and lets the owner train the AI on their own policy. AegisAI is the only product designed to do all three.

Closest in concept, and where they stop

Elastic Security and Wazuh come closest on openness and data control: both can keep data on the customer’s own servers and both can connect a locally hosted language model. But the model runs on a server the customer has to build and run, it serves an analyst at a dashboard, and tuning it is the customer’s own machine-learning project. Neither puts a language model on the protected machine or offers a guided, tested, reversible fine-tuning workflow.
SentinelOne is the strongest commercial platform and, since March 2026, offers on-premise and air-gapped editions for regulated sites. Its generative AI, Purple AI, remains an assistant for analysts on the SentinelOne platform, and its models are trained by SentinelOne for all customers.
CrowdStrike and Microsoft have the largest generative-AI investments in the category — Charlotte AI and Security Copilot — and both run them in their own clouds, metered per analyst seat, per action or per compute unit, on top of the endpoint subscription.
Arctic Wolf Aurora (Cylance) and Norton show that on-device AI works: Cylance pioneered offline machine-learning prevention, and Norton runs NPU models for deepfake and scam detection on AI PCs. Neither runs a language model that reads, explains and acts on endpoint incidents, and neither lets the customer train it.
