Micro-Segmentation

Micro-segmentation

Segmentation that
writes itself.

The endpoint agent learns your network on its own, drafts the rules for you, shows you exactly what they would block — and only then, when you say so, enforces them. No VLANs. No ACL project. No downtime.

The same policy, three safe steps.

Nothing is ever blocked by surprise. Switch between the modes below to see exactly what the agent does to real traffic at each stage.

Endpoint flow policy Learning
The agent is recording every flow and building a baseline. Nothing is blocked, nothing is changed, users notice nothing at all.

How the learning works

No one writes the first rule.

The agent already sees every TCP connection the host makes. Segmentation is just what you do with that knowledge.

Step 01

Observe flows

Every TCP connection is recorded with source, destination, port, process and frequency.

Step 02

Cluster hosts

Machines with the same behaviour are grouped automatically — finance, engineering, servers.

Step 03

Draft the rules

A first-match ruleset is generated with a confidence score and evidence for every line.

Step 04

Keep adapting

New applications and servers are detected and proposed as amendments, not incidents.

Rule proposals

You review. You approve. That's the work.

Every proposed rule arrives with the evidence behind it and a confidence score. Approve them one by one, or take the whole baseline in a click.

Why it is easier

The same outcome, without the project.

Traditional segmentation

Months of work
  • Map the network by hand, or guess
  • Re-architect VLANs and subnets
  • Write and maintain ACLs per switch
  • Change windows, downtime, rollback plans
  • Break something and find out from the helpdesk
  • Documentation goes stale the week it ships

ReviveSec micro-segmentation

A week, mostly waiting
  • The agent maps every flow automatically
  • Nothing on the network changes — enforcement is on the host
  • Rules are drafted for you with evidence and confidence
  • No change window, no downtime, no reboot
  • Observe mode shows the impact before anything is blocked
  • The baseline keeps adapting as the estate changes
Under the hood

Host-level enforcement, done properly.

First-match TCP rules

Deterministic evaluation by IP, CIDR, port and direction — the same model your firewall team already thinks in.

Automatic host grouping

Machines are clustered by observed behaviour, so policy follows the role rather than the IP address.

Lateral movement blocking

SMB, RDP, WinRM and NetBIOS between peers closed by default once the baseline says they are unused.

Per-group policy

Finance, engineering and servers each get their own ruleset, versioned and rolled out on the next heartbeat.

Instant rollback

Every policy is versioned. If a rule bites, roll the group back to the previous version in one click.

Works anywhere the agent runs

Windows and Linux, on-premises, remote and cloud workloads — no dependency on where the machine sits.

Let it learn your
network first.

Seven days in silent mode, then look at what it drafted. You decide whether to enforce a single line of it.
