Prophet Security's AI SOC learns from your alerts.
Simbian also learns from the attacks it runs.
Prophet Security and Simbian are both AI SOC platforms that triage and investigate every alert, respond under approval rules you set, hunt threats, and write and tune detections. Simbian is self-improving defense: what its AI Pentest Agent proves by attack tells the SOC which alerts matter, and its AI Detection Engineering Agent proposes the missing detections for a human to approve.

Prophet Security answers 3 of the 4 SOC questions
Simbian's self-improving defense runs a four-node loop that asks what an attacker could do, whether it already happened, whether the SOC would catch it, and whether it can be caught next time. Prophet's agents cover the last three.
What both do
- ●Alert triage and investigation on every alertBoth record the reasoning and evidence behind each verdict.
- ●Incident response under rules you setThe verdict drives the response. You decide which actions run without anyone signing off.
- ●Threat hunting and detection engineeringBoth hunt in plain language and write and tune rules in the SIEM you already run.
- ●Learning your team can reviewAnalyst guidance and corrections shape later investigations. Your SOC team sees each change before it lands.
Where Simbian pulls ahead
- ▸An AI Pentest Agent on the same platformIt attacks your web applications, and an alert that exploits a weakness it proved is investigated as high severity.
- ▸Detection gaps proven by attackWhen a pentest gets in and no alert fires, the AI Detection Engineering Agent proposes the missing rule that day.
- ▸Detections before a CVE existsA flaw with no CVE yet is simulated in Simbian's war lab, without your data, and becomes a proposed detection.
- ▸On-premises or air-gapped, with your own LLMRun it in your datacenter or fully offline, on the model you pick, with no call-home.
How is Prophet AI built differently from Simbian?
Prophet AI runs three defensive products and an optional human service, Watchtower, as dedicated single-tenant SaaS with an optional data plane in your cloud, while Simbian runs its four-node loop as SaaS, as single-tenant SaaS in your VPC, on-premises, or fully air-gapped.

How does Prophet Security compare with Simbian?
On Prophet's published material as of November 2026, Prophet Security leads three of 18 rows: backtesting, stated integrations, and a 24x7x365 expert service. Simbian leads seven, five of them from the AI Pentest Agent and the war lab. The other eight score the same.

Frequently Asked Questions
Prophet Security is the company behind Prophet AI, an agentic AI SOC platform, and it launched publicly in April 2024. It raised a $30 million Series A led by Accel in July 2025 and took strategic investment from American Express Ventures and Citi Ventures in February 2026. Its agents investigate every alert, take the response actions a customer has approved, hunt for threats, and write and tune detection rules. An optional service, Watchtower, adds human experts.
Offense is the main difference between Prophet Security and Simbian: Simbian runs an AI Pentest Agent, and Prophet AI publishes no offensive product. Each cycle the pentest runs techniques, the AI Threat Hunt Agent checks the logs, the AI SOC Agent is scored on what it caught, and the AI Detection Engineering Agent proposes rules for the misses. At one customer, coverage of the MITRE ATT&CK techniques tested rose from 33% to 56% to 83% over three cycles.
Prophet Security triages and investigates every alert autonomously, and it responds only within limits a customer sets. According to Prophet's AI SOC Analyst page, Prophet AI “investigates autonomously from day one, but only takes actions you've approved.” Simbian's AI SOC Agent also acts only within limits you set. Every alert gets a verdict with the evidence attached, and your team decides which actions run without approval.
No, as of November 2026. Prophet AI's products are the AI SOC Analyst, AI Threat Hunter, AI Detection Engineer, and the Watchtower service, and none of them attacks your environment. Prophet's October 2026 guide, What Is Agentic SOC?, lists adversary emulation under “Where the Agentic SOC Goes Next.” Simbian's AI Pentest Agent tests web applications and hands its findings to the AI SOC Agent and the AI Detection Engineering Agent.
No on-premises or air-gapped option appears in Prophet Security's published material as of November 2026. Prophet documents dedicated single-tenant SaaS, a data plane that can run in your own cloud, and bring-your-own-key encryption. According to SACR's 2026 AI SOC Technoscope, it uses frontier models rather than a proprietary foundation model. Simbian runs on-premises or fully air-gapped. You bring the LLM, and your data doesn't leave your network.
Prophet positions Prophet AI as an alternative to MDR. Watchtower, its optional human layer, has experts review every malicious and inconclusive determination, 24x7x365, and they can execute containment if you choose. Simbian's AI SOC Agent provides 24/7 coverage, and you can run it yourself or buy it through a provider. MSSPs deliver about 280 of Simbian's 300+ enterprise environments.
Run Prophet AI on your own alerts and read the reasoning behind each verdict, including the false positives it closes. Then test what investigation doesn't cover. Who attacks your applications and feeds the findings to the SOC? Does a gap exposed by a pentest become a proposed rule? Check whether it proposes detections for flaws with no CVE yet and learns from attacks it simulates, not only your own history.
The closest Prophet Security alternatives are AI SOC platforms such as Simbian, Dropzone AI, 7AI, and Exaforce. Compare each on alert investigation, approved response, hunting, and detection engineering. Of those four, Simbian is the one that sells AI penetration testing as a product on the same platform.
Simbian, because it is self-improving defense. Its AI SOC Agent investigates and responds to every threat, on average under 4 minutes from detection to response. It shares a platform with an AI Pentest Agent, an AI Threat Hunt Agent, and an AI Detection Engineering Agent. Each attack the AI Pentest Agent runs is scored against what the SOC caught, and the next run shows whether the fix held.
