Identity alerts, triaged and contained — with the evidence attached.

Theo works the identity alert queue your Microsoft 365 and Entra tenants already produce. It gathers the evidence, writes what it found, and proposes the containment. Containment is approval-gated by default.

Where incidents actually happen

It's identity. Almost every time.

The security incidents that land on an MSP are not exotic. They are a credential that got phished, a session that got stolen, an MFA prompt that somebody approved at the fourteenth attempt because they wanted the noise to stop.

The tenant usually tells you. Entra raises a risky sign-in, an impossible-travel detection fires, a mailbox rule appears at 2am. The alert exists. What is missing is somebody to work it in the twenty minutes that matter.

Theo works it. The evidence is gathered before anyone reads the alert.

01

Impossible travel and unfamiliar sign-in properties

An account authenticating from two continents inside an hour, or from a client app and location it has never used.

02

Risky sign-in and risky user detections

Entra has already scored it. The question is what the sign-in history around it looks like, and whether anything changed in the mailbox afterwards.

03

MFA fatigue

Repeated push denials followed by one approval. That pattern is a compromise, and it looks like nothing in a dashboard of counts.

04

Suspicious inbox rules

Rules that move anything matching "invoice" or "payment" into a folder nobody opens. This is the step between access and fraud.

05

External mail forwarding

Mailbox-level or transport-level forwarding to an address outside the tenant, set quietly, often weeks before anything else happens.

How an alert gets worked

Investigate autonomously. Contain on approval.

Reading a sign-in log changes nothing, so investigation does not wait for anybody. Containment changes a client's tenant and locks a real person out of their work, so it does.

STEP 1

Alert intake

Identity alerts from Microsoft 365 and Entra, device alerts from Datto RMM and NinjaOne. Each one becomes a ticket in your PSA.

STEP 2

Evidence gathering

Sign-in logs, risk state, inbox rules, forwarding changes, session and MFA method inventory, and what the account can reach.

STEP 3

Containment recommendation

The action Theo recommends, the scope, what it will do to the user, and the evidence behind it. Approve, change the scope, or decline.

approval-gated
STEP 4

The written record

What fired, what the evidence showed, what was contained, who approved it, and what is still open — in the PSA.

Investigation runs on every alert, including the false positives.

Most identity alerts are noise. Working them anyway is how you find the one that isn't — and a dismissed alert with the evidence attached is a decision you can defend later.

The AI Security Engineer
Containment

Four actions that stop the incident.

Revoke the sessions. Disable sign-in. Remove the malicious forwarding rule. Revoke the MFA methods that were registered by whoever is not the user. Done in the right order, that is the incident over.

Each one is staged with its scope and its evidence, and each one waits for a named approver. Revoking MFA methods is not reversible, and it keeps its gate in every configuration.

Read-only investigation is autonomous. No approval, no waiting, nothing changed.
Containment is approval-gated by default on every client and every alert type.
MFA method changes stay gated permanently. That is not a per-client setting.

Reversible means a technician can restore the previous state. It does not mean the containment was free — a session revocation still signs somebody out of their day, which is exactly why a human decides.

Evidence and compliance

Timestamped, attributed, exportable.

A contained account with no written record is a problem you will have again, and an answer you will not have when the client, their insurer or their auditor asks.

Timestamped action log

Every read and every write, in order, with its arguments and its result. 100% of actions are logged, including the investigation steps that found nothing.

Named approver on every action

Containment carries the name of the person who authorised it. "The tool did it" is not an answer anybody accepts after an incident, and it is not one you have to give.

Exportable

Per client, per date range, per incident. Attach it to a client report, an insurer's questionnaire or your own compliance file without rebuilding the timeline by hand.

On our own posture.

Your client data is not used to train models. SOC 2 Type II — Trust Center. Data residency, retention window and the subprocessor list are in the trust pack we send before any pilot. Theo acts through the same delegated permissions your technicians use, scoped per client, and you can revoke access from your side at any time.

Straight answers

It is not a SIEM. It is not an EDR.

It is not a replacement for your security stack. If we are not clear about that now, you find out six weeks in, and that is a worse conversation.

What it does
  • Works the identity alert queue from Microsoft 365, Entra and your RMM.
  • Investigates autonomously — sign-in logs, risk state, inbox rules, forwarding, sessions, MFA methods.
  • Proposes containment with the evidence attached and executes on approval.
  • Writes the incident record in the PSA, with a named approver on every action.
  • Exports the trail for client reporting and compliance evidence.
What it isn't
  • Not a SIEM. It does not ingest, store or correlate raw log volume.
  • Not an EDR. It does not sit on the endpoint and does not detect on the endpoint.
  • Not a replacement for your security stack. It needs your detections to work at all.
  • Not a SOC. No 24/7 human analyst coverage, no threat hunting, no advisory.
  • Not autonomous on containment. By default, and permanently on MFA method changes.

Keep your SIEM, your EDR and your security partners. Theo works the queue they generate, on the identity side, where most MSP incidents actually start.

Objections

The questions a security lead asks.

Not by default, on any client or any alert type. Containment is approval-gated, and revoking MFA methods is gated permanently because it cannot be undone.

Some MSPs eventually grant autonomy on session revocation for specific clients, because it is reversible and the cost of waiting is high. That is a decision you make deliberately, per client, after watching it work.

Investigation is read-only, so the cost of a wrong target is a wasted read rather than an incident. Theo resolves the alert to a real identity in the tenant before it starts, and the resolution is on the ticket for you to check.

Containment names the exact target and its scope at the approval gate, so a mismatch is visible before anything executes.

Yes. Theo does not ingest or retain log volume and does not do correlation or detection engineering. It consumes the alerts your stack produces. If you turned the stack off, Theo would have nothing to work.

Microsoft 365 and Entra for identity, Google Workspace for identity where that is the tenant, and Datto RMM and NinjaOne for device alerts. ConnectWise Automate and N-able are on the roadmap.

If your source isn't on that list, say so on the call and we'll be straight with you about timing rather than about intent.

The named approver. That is the point of the gate. Theo's job is to make the decision a ten-second one by putting the evidence and the recommendation in front of the right person; the judgement stays with your team.

The 2:14am alert gets investigated either way.

Book 30 minutes. We'll look at the identity alerts your tenants generate in a typical week and which of them Theo should be working end to end.
