Threat Monitoring and Response

Nothing announces the week before the fraud.

Prevention products are excellent at the loud attacks and mute about the patient ones. An intruder who signs in with a password bought from a broker has tripped nothing. No file landed, no signature matched, and every control in the path behaved exactly as its vendor intended, because from the outside the session is indistinguishable from your operations manager checking mail from a hotel.

What follows in this industry has a recognisable shape. The intruder reads before acting. They learn which client is funding, which partner signs off, how your firm phrases a payment instruction, and which week the person who would question it is away. A rule is added that files the genuine replies out of sight. Then one message goes out with different bank details on it, and the loss is realised by a colleague doing exactly what the procedure told them to do.

The whole opportunity to intervene sits inside that reading period, and it runs in days rather than months. Shutting it takes two things no product delivers by itself: detection that reasons about behaviour instead of matching known-bad files, and somebody whose job is to read the output at the hour it lands.

Judgement happens twice: once on the machine, once by a person.

The SentinelOne agent goes onto whichever machine a line covers, and the first judgement is made there. For a workforce that works from client offices, kitchen tables, and departure lounges that placement is the whole point: cover does not thin out because a laptop cannot phone home.

Whatever the agent produces lands in Fluency, our correlation layer sitting behind every line here. Its job is to stop a detection being a solitary fact. One credential authenticating from a city nobody visited, a second machine reaching the same address, an inbox rule written forty minutes before either: separately those are three shrugs, and together they are a case. Fluency assembles them and passes the assembly to the Fortify 24x7 desk, which never closes. An analyst works out whether somebody at your firm genuinely did this, and calls your named contacts when the answer is no. Author and clock time are attached to every step, and that attachment is what your program file will want later.

• Watch lines hand you the agent, the alerting, and the review. Your own people do the remedial work, with our analysts talking them through it.
• Correlated lines extend the field of view past the machine into mailboxes, servers, workloads hosted on Amazon, Microsoft, and Google clouds, network flow, and the directory, then read all of it as one narrative. Six modules ride along: antivirus of the newest generation, detection and response at the endpoint, analytics reading the behaviour of users and of entities, inspection of network traffic, cover for cloud workloads, and a layer handling security events.
• Remediation lines put the work back on us. Containment and cleanup for every confirmed event are done by our analysts, so nobody at your firm is opening a console on a Saturday afternoon.
• Node lines carry the identical cover onto Kubernetes hosts, where reconciliation jobs and reporting pipelines increasingly live.

Match the line to what the machine can reach.

Very few firms should put one line everywhere. Two questions settle it: what can this machine touch, and who is awake when it starts behaving oddly.

• Endpoint Detection Watch fits firms with technical people who can respond inside office hours, on machines that hold client records without being able to move a dollar.
• Correlated Estate Detection fits firms that want the mailbox, the server, the cloud, and the directory read against the endpoint, which is the only arrangement in which a takeover looks like one event instead of four disconnected ones.
• Detection with Analyst Remediation fits firms carrying no security staff, and it belongs on anything that can release a payment, open the custody platform, or reach the client file store.
• The node lines are counted per cluster node and belong on the hosts themselves, never on the desktops that query them.

Running different lines side by side is ordinary and costs nothing extra. Counts are edited in the portal as hardware arrives and leaves, and the edit shows up on the next invoice.

One escalation, from first signal to written record.

Two in the morning, and a credential authenticates from a country where the firm has never had a client. Nothing downloads. A rule appears that files anything mentioning remittance into a folder no one has opened since it was created, and the session closes. By itself that is a single row in a log which, realistically, surfaces at next year's review or not at all.

Read together it is unambiguous. Fluency already holds the sign-in, the new rule, and the fact that the same credential was used from your own office ninety minutes beforehand. Within minutes an analyst has that sequence in front of them, and on a remediation line the session is terminated, the rule is deleted, and the credential is flagged before any genuine remittance ever arrives.

Whichever line you hold, the day ends with a dated account of what occurred, what was done, and what got ruled out. That document carries the same weight as the containment, since it is what somebody asks to see months afterwards.
