ActiveFlux — agentic cloud security
Keep production secure.Continuously.
ActiveFlux is agentic cloud security built to monitor, protect and assure your production environment in real time. It detects meaningful changes, understands their impact, and can close high-risk misconfigurations before they become persistent exposure.

Reduce the complexity of securing cloud.
The problem
Posture reports describe the drift. They do not stop it.
Cloud environments change thousands of times a week, mostly by people with legitimate access doing legitimate work. A tool that tells you on Monday what changed on Friday has documented an exposure, not prevented one.
Change is constant and mostly benign
The hard part is not detecting change. It is separating the routine from the change that alters what an attacker can reach.
A finding is not an impact
A public bucket matters or does not depending on what is in it and who can reach it. Without that context, every misconfiguration reads the same.
The window is minutes, not weeks
By the time a misconfiguration reaches a report, it has been reachable for days. Response has to happen where the event happens.
Nobody trusts automation they cannot undo
Teams disable auto-remediation because it is opaque. Automated action is only acceptable if it is scoped, recorded and reversible.
What it does
What ActiveFlux does
Detect meaningful change
Cloud environments move constantly. ActiveFlux separates the routine from the change that alters your security posture.
Understand the impact
A new permission or an opened port is read against the graph: what it now reaches, what it exposes, and which paths it creates.
Close high-risk misconfiguration
Where the risk is clear and the action is safe, the agent restores the secure state rather than filing it for later.
Assure it stays that way
The secure state is held and re-proved as the environment keeps moving. Drift is a condition to be corrected, not a report to be read.
How it reasons
From an audit event, to an understood change, to a closed exposure.
Three diagrams, not screenshots. The product demo shows the real interface.
- DETECTEDA bucket is made publicAn audit event arrives. Someone with legitimate access made a legitimate-looking change.
- UNDERSTOODWhat it now reachesRead against the graph: what data sits there, who can reach it, which paths this opens.
- ACTEDAccess returned to privateA safe, enabled guardrail action. Recorded, attributed and reversible.
- ASSUREDThe state is heldThe posture is re-proved, and the same drift is watched for its return.
The difference between a posture report and protection is step three.

The loop
Posture is not a report. It is a state you hold.
SEE
Accounts, workloads, identities and configuration, in real time.
UNDERSTAND
What a change means for exposure, blast radius and reachable paths.
ACT
The secure state is restored, with the change recorded and reversible.
ASSURE
Continuous proof that production is still in the posture you agreed to.
Who it’s for
Who has to trust the automation.
An agent that changes production configuration has to earn permission from three different people, each for a different reason.
Security leadership
You need to know production is in the posture you signed off on, and to prove it continuously rather than at audit time. Every automated action is recorded and attributable.
Cloud security engineers
You need change evaluated against impact, not matched against a rule list. Incidents arrive with the asset, the identity, the blast radius and the remediation on one record.
Platform and DevOps
You need to know exactly what the agent is allowed to touch. Guardrails are opt-in per rule, scoped to safe actions, and reversible — you decide what automation is permitted before it is.
Getting started
Observe first. Automate when you trust it.
Nobody should turn on automated remediation in production on day one, and we do not ask you to.
Start · the first day
Connect one account, read-only
A read-only role on a single cloud account. ActiveFlux starts watching change and building the picture; it can change nothing.
Then · the first weeks
Watch what it would have done
Guardrails run in observe-only. You see which changes it would have reverted, and why, before granting it the ability to.
After that · when ready
Enable guardrails, one at a time
You enable specific safe actions per rule. Each run is logged with its status and execution time, and failures say plainly that exposure may remain.
Datasheet
The technical answer.
- Deployment
- Agentless, via cloud provider roles. Read-only by default; write actions are enabled per guardrail.
- Cloud coverage
- AWS, Azure and GCP.
- Event sources
- AWS CloudTrail, Azure Activity Log and Google Cloud Audit Log events, evaluated by real-time monitoring rules.
- Automated response
- Safe actions run only when a rule matches and the action is enabled. Every run is recorded with its status and execution time; failures report that exposure may remain.
- Outputs
- Incident records with asset, identity and impact context; guardrail action log; posture assurance history.
- Integrations
- GitHub, GitLab, AWS, GCP, Azure, Slack and Jira.

Start your trialQuestions
What people ask before they say yes.
- Will it change our production configuration?
- Only the specific actions you enable, per rule, after you have seen them run in observe-only mode. Read-only is the default and a perfectly reasonable place to stay.
- What happens when an automated action fails?
- It is reported as failed, with the implication stated: exposure may remain. A silent failure would be worse than no automation, so failures are surfaced, not smoothed over.
- Can we undo what the agent did?
- Yes. Every action is recorded with what changed, when, and under which rule, and is reversible. Automated does not mean unaccountable.
- How is this different from a CSPM?
- A CSPM tells you the posture. ActiveFlux is built to hold it — detect the change, reason about its impact against the graph, and close it. The reporting is a by-product, not the product.
- Which clouds and events do you support?
- AWS, Azure and GCP, evaluated from CloudTrail, Azure Activity Log and Google Cloud Audit Log events. The datasheet above carries the specifics.
- What does it cost?
- We scope pricing to your estate. Contact us to start your trial and we will be specific.
Alongside the suite
Production, held to a state.
ActiveFlux stands alone: connect a cloud account and it monitors, protects and assures that environment on its own. It shares the platform’s model of assets, identities and controls, so as the suite converges a cloud change will also be read against what Ore Hammer sees from outside and what SentinelFlow shipped from the repository.
