Incident Response & Breach Containment

You've been breached.
Now what?

Someone's in your email, a server is encrypting itself, or a tool you've never heard of is running as an administrator. We stop the bleeding, find out how far it went, and tell you in plain language what happened — the same engineers, whether you're a client or you found us in an emergency.

The problem

The worst time to figure out who to call

Most businesses discover their incident response plan doesn't exist at the exact moment they need it. The bookkeeper notices an invoice was paid to the wrong account. A workstation starts behaving strangely. Someone gets a call from a customer asking about an email nobody sent.

What happens in the next few hours decides how much this costs. Pull the wrong plug and you destroy the evidence you need. Wipe the machine and you lose the answer to how did they get in — which means it happens again. Do nothing and the attacker keeps working, because they usually still have access.

AllTech responds to active incidents: contain it, understand it, remove it, and document it. If we already manage your environment, we're often the ones who find it first.

What you get

Containment, investigation, and a straight answer

Handled by our own engineers using the tools we already run — endpoint detection, remote management, and network monitoring — not a subcontracted forensics firm you've never spoken to.

Immediate containment

We isolate affected systems from the network while keeping them powered on and intact. The attacker loses access; the evidence stays where it is.

Account lockdown

Compromised accounts get password resets, revoked sessions, and re-enrolled multi-factor authentication. Attackers hold onto stolen sessions long after a password changes — revoking them is what actually ends the access.

Hunting the persistence

Removing the malware is the easy part. We go after what it left behind: scheduled tasks, registry run keys, rogue services, mailbox rules, and remote-access agents installed to survive a cleanup.

Scope, not guesswork

We determine which systems were touched, which accounts were used, what data was reachable, and whether it spread to cloud storage or other locations — instead of assuming it was just the one PC.

Surgical remediation

Where we can, we remove exactly what’s malicious and leave the rest running. Reimaging is sometimes the right call, but it shouldn’t be the automatic one — a production machine you can’t rebuild quickly deserves the more careful approach.

A written debrief

You get a document: timeline, what was found, what we did, what’s still open, and what to change so it doesn’t happen again. It’s the thing your insurer, your attorney, and your board will ask for.

In the field

Patterns we see over and over

All identifying details removed.

The mailbox rule nobody could see

A compromised Microsoft 365 account. The attacker didn’t send obvious spam — they created an inbox rule that quietly moved every message mentioning the company’s accounting software into a folder nobody opens. The point wasn’t the mailbox. It was to hide the payment-redirection conversation from the one person who’d have noticed it. We found it while investigating malware on the same user’s workstation, removed the rules, revoked every active session, and recommended a 90-day review of the account’s financial activity.

Legitimate software, doing illegitimate things

A remote-access agent — the same category of tool IT departments use every day — was installed on a workstation and pointed at a server the attacker controlled, running with full system privileges. The loader that installed it was a renamed copy of a standard Windows program, so nothing on disk looked obviously wrong. No automated alert caught it. An engineer doing a routine review of security tool exclusions did. The host was isolated the same day, and a scripted cleanup removed the rogue service, the scheduled task, and the registry keys it used to restart itself.

In both cases, the thing that caught it was a person or a behavior rule — not a signature. Nothing here was a virus a scanner had a name for.

The uncomfortable part

Why finding it is only the first hour

Security tools generate alerts. That's the beginning of the work, not the end of it. An alert tells you something happened on one machine at one moment. It doesn't tell you whether the attacker still has access, what else they touched, which credentials they took, or what they left behind to get back in.

That gap is where incidents get expensive. Malware gets quarantined and everyone relaxes — while the remote-access tool it installed keeps running, the mailbox rule keeps hiding emails, and the scheduled task reinstalls the payload overnight.

It's also why speed matters more than it seems. Attackers commonly sit in an environment for days or weeks before anyone notices, and every one of those days is more accounts, more credentials, and more places to hide. The goal of response isn't just removal. It's removing every way back in, and knowing you did.

How it works

What happens when you call us

01

We answer

You get an engineer, not a ticket confirmation. First questions: what are you seeing, what’s still running, and what shouldn’t be touched yet.

02

We contain

Affected systems get isolated from the network and accounts get locked down. Isolated, not wiped — we keep the machine intact so we can still find out what happened.

03

We investigate

We work out how it got in, what it ran, where it spread, and whether it’s still active. That includes the parts people forget: cloud storage that synced the file, other devices on the same account, and mailboxes.

04

We eradicate

Malicious files, rogue services, scheduled tasks, registry keys, mailbox rules, and any remote-access agent that isn’t supposed to be there. All of it, verified afterward — not just the file that triggered the alert.

05

We restore

Systems come back to a known-good state and back onto the network, with the credentials that were exposed treated as compromised and rotated.

06

We debrief

A written report and a conversation. What happened, what we did, what’s still open, and the specific changes that would have prevented it or caught it sooner.

The deliverable

An incident nobody documented is an incident that repeats

Every response ends with a written debrief, and it isn't a form letter. It contains a timeline with real timestamps, the technical findings, the business impact in plain terms, every remediation action taken, and the recommendations that follow from what we actually found — not a generic security checklist.

Timeline What happened, when, in order.
Findings What was on the systems and what it was built to do.
Impact Which accounts, which data, and what to assume was exposed.
Actions taken Every containment and remediation step, on the record.
What’s still open The honest part: what we couldn’t determine, and what needs follow-up.

This is also the document that gets requested later, and usually at a bad moment: by a cyber insurance carrier processing a claim, by an attorney assessing notification obligations, or by a customer's security team asking what happened to their data.

Who this is for

Built for real situations

A business that just found something

Odd emails, a strange login alert, a machine acting wrong. You don’t need to be a client and you don’t need to be sure it’s real. Call before you start deleting things.

A company whose money went to the wrong account

Business email compromise is the quietest and most expensive incident we handle. There’s a narrow window where the payment can still be recalled, and it closes fast.

A manufacturer that can’t stop the line

Containment doesn’t have to mean shutting down production. We isolate what has to be isolated and work around what can’t be, deliberately.

A healthcare or professional services office

Patient records and client files carry notification obligations if they’re exposed. Determining what was actually reachable — rather than assuming the worst — changes what you’re legally required to do.

A business whose insurer is asking questions

Cyber policies increasingly require documented response procedures and a written incident record. We produce both.

An organization with no IT staff on-site

Multi-location businesses and small offices where nobody local can tell a real incident from a pop-up. We assess it remotely and come on-site when hands on hardware is what’s needed.

A company that already cleaned it up

Ran a scan, deleted the file, moved on — and something still feels wrong. Usually because the persistence is still there. We’ll verify it’s actually gone.

A business that wants a plan before an incident

The cheapest hour of incident response is the one spent before anything happens: who gets called, what gets isolated, where the backups are, and who talks to customers.

Honest expectations

What we don't promise

We don't promise your data wasn't taken. In most incidents, proving a negative isn't possible with the evidence available, and any firm that tells you otherwise on day one is guessing. What we can do is establish what was reachable and what the malware was built to do, and tell you which assumptions are safe.

We don't promise a fixed recovery time. It depends on how long the attacker had, how many systems were involved, and whether your backups are usable — and we'd rather tell you that than quote a number we invent to win the call.

We're not a law firm and we're not your insurer. We'll document what happened accurately enough for both, and we'll tell you when it's time to involve them, but breach notification is a legal determination and we don't make it for you.

And we'd rather you never need this page. Response is the most expensive layer of security there is. Monitoring, patching, backups you've actually tested, multi-factor authentication, and training are all cheaper than the day you call us — which is why we spend most of our time on those instead.

If something's happening right now, call. Don't email.

If it's not urgent, let's build the plan before you need it — who gets called, what gets isolated, and how you keep the business running while we work.
