Ransomware protection for US businesses

Protect your business from ransomware: prevention, detection, response, recovery.

Ransomware remains the most damaging cyber threat facing US mid-market businesses, and the pattern behind most successful attacks is consistent: weak email controls, missing MFA, and no backup discipline. We deliver layered ransomware protection covering prevention (close the gaps), detection (find it fast), response (contain it cleanly), and recovery (restore without paying), built on the Microsoft security stack you already license.

Four layers of ransomware defense

Prevent, detect, respond, recover. All four matter.

Single-layer defense fails. We build all four layers because ransomware groups have all four phases in their playbook. Strong prevention reduces incident volume; strong detection cuts detection-to-containment time; strong response limits damage; strong recovery breaks the extortion model.

Prevention: close the entry points

Microsoft Defender for Endpoint EDR on every workstation, Defender for Office 365 on every mailbox, MFA enforced everywhere, Conditional Access restricting access to trusted devices and networks, a patch management cadence, and application control on critical hosts. These are also the controls cyber insurance applications now ask about by name.

Detection: find it before encryption starts

Microsoft Sentinel SIEM with ransomware-specific analytics rules, 24/7 SOC monitoring, behavioral-anomaly detection for unusual file-access patterns, recurring threat-hunt cycles, and IOC matching against global threat-intelligence feeds.

Response: contain fast, escalate cleanly

A written incident-response playbook, on-call engineer engaged within 5 minutes of a P1 alert for managed clients, isolation procedures for compromised endpoints, forensic preservation, breach counsel and insurer coordination, and a communication plan for staff and customers.

Recovery: restore without paying

Immutable, off-site backup with quarterly restore tests, designed to RPO 24 hours and RTO 4 hours for critical systems. The recovery procedure is tested in tabletop exercises before incidents, not learned during them.

Why US businesses route ransomware protection through us

Four reasons IT leaders choose GR for ransomware defense.

Microsoft-native defense stack

Defender XDR, Sentinel SIEM, Purview classification, Entra Conditional Access, immutable Azure Backup. All native to your existing Microsoft tenant, no third-party agents fighting each other, and one console for the people watching it. Most of it sits inside licensing many US businesses already pay for.

Tested incident-response playbook

Not a paper plan. Quarterly tabletop exercises, an annual full simulation, and post-incident reviews from real response work. The playbook is rehearsed by the people who would run it, which is the difference between a plan and a document.

24/7 monitoring with 5-minute P1 response

Sentinel ingests signals around the clock. P1 alerts reach a named on-call engineer within five minutes for managed clients, and containment actions start immediately after triage. The clock that matters in ransomware is detection-to-containment; we minimize it.

Security awareness training as part of the engagement

The most common ransomware entry point is phishing. We deliver role-based awareness training, run simulated phishing campaigns, and report click-rate trends to your leadership so the human layer measurably improves alongside the technical ones.

High-risk profiles

Six business profiles where ransomware is highest-risk.

Professional services and SMBs

Law firms, accounting practices, and mid-market companies. Heavily targeted because operational pressure and client confidentiality incentivize paying.

Healthcare providers

Patient-data sensitivity, HIPAA exposure, and clinical-operations urgency. High-value targets with high pay-pressure.

Financial services and fintech

Client-data sensitivity, regulatory expectations including GLBA and state rules, and reputational risk. Strong defense is table stakes.

Manufacturers (OT exposure)

Plant-floor systems now connected to corporate IT. Production downtime cost makes ransom payment financially tempting; strong OT segmentation is essential.

Multi-location retailers

POS networks across sites, customer-data stores, and payment infrastructure. Wide attack surface with peak-season exposure.

Critical-infrastructure operators

Energy, water, and utility-adjacent operators. Highest-impact targets that draw the most capable adversaries.

How a ransomware-protection engagement runs

From readiness audit to ongoing defense.

Layered defense is a program, not a project. The initial audit baselines your current posture; the foundation build closes the most exploitable gaps; ongoing operations keep the defense current as threats evolve.
  1. 1

    Ransomware-readiness audit

    1-2 weeks

    Map the current state across the four layers: prevention controls, detection capability, IR playbook maturity, and recovery capacity. Output: a written gap report with a prioritized remediation roadmap, which doubles as evidence for your insurance renewal.

  2. 2

    Foundation build (close the gaps)

    4-8 weeks

    Defender XDR deployed, MFA enforced everywhere, Conditional Access policies applied, Sentinel operational, immutable backup configured with a restore-test schedule, the IR playbook written, and awareness training rolled out.

  3. 3

    Tabletop exercise and drill

    1 day

    A live tabletop with leadership: a simulated ransomware scenario walked through end to end. The IR playbook is tested, gaps identified, and the communication chain validated. First of a quarterly cadence.

  4. 4

    Ongoing defense operations

    Continuous

    Monthly threat hunt, quarterly tabletop, semi-annual restore test, continuous Sentinel monitoring, and security-awareness training rolled to new hires.

Ransomware protection FAQ

What IT leaders ask before engaging.

No. Modern ransomware groups bypass legacy AV routinely. Antivirus is one layer in a multi-layered defense; alone, it leaves you exposed at the email vector, the credential-theft vector, the lateral-movement phase, and the backup-deletion phase. Layered defense is the minimum bar, and it is also what cyber insurance underwriters now expect to see.

It is scoped per engagement against your size and risk profile, and it is a small fraction of what an incident costs. Real ransomware incidents carry ransom pressure, recovery labor, business interruption, legal and notification costs, and reputational harm, and the total routinely dwarfs years of defensive spend. We provide a custom quote after the readiness audit, when the actual gap list is known.

That is an incident response engagement, and speed matters more than anything else. Contact us immediately and mark it urgent; emergency engagement starts remotely the same day, which is how containment actually happens: tenant-level isolation, credential resets, and endpoint containment executed over secure remote access. Then forensic preservation, recovery from backups, and coordination with your breach counsel and insurer. Whether to pay is your call, made with counsel; our advice is no unless backups have failed.

6-10 weeks for a comprehensive foundation build. The most exploitable gaps close in the first three weeks (MFA enforcement, EDR deployment, immutable backup). Sentinel monitoring is operational by roughly week six, and the IR playbook and first tabletop land by week eight. Ongoing operations run from week ten.

Directly. Underwriters ask about specific controls by name: EDR coverage, MFA enforcement, immutable or offline backups, a tested incident response plan, and security awareness training. This engagement implements those controls and produces the evidence pack the application and any follow-up questionnaire ask for. Better answers on those questions generally mean better terms, though pricing decisions belong to your carrier and broker.

Defender XDR (Defender for Endpoint, Office 365, Identity, and Cloud Apps) is enterprise-grade and is what we deploy as the default. It compares well with third-party EDR platforms and integrates natively with the rest of the Microsoft stack, which most US businesses already license in part. Third-party tools have specific niches, but Defender is the right baseline for most mid-market environments.

Immutable backup is specifically designed to survive this. Backups are stored off-site under a write-once-read-many policy with separate authentication, isolated from your production identity plane. A ransomware group cannot encrypt or delete them even with full domain admin on your primary environment. Quarterly restore tests verify the model actually works.

Our strong recommendation is no. Paying funds further criminal activity, marks you as a willing target for repeat attacks, and does not guarantee decryption. Payments can also create sanctions exposure where the recipient is a sanctioned entity, which is a determination for your counsel, and many carriers require their consent before any payment. Our defense design prioritizes recovery without paying; if backups have failed and pressure is extreme, we coordinate specialist negotiators and law enforcement with your counsel.

Possibly, and it is a legal determination, not a technical one. Every US state has a breach notification statute, HIPAA adds obligations for covered entities, and public companies carry SEC disclosure duties for material incidents. Our role is establishing the technical facts fast: what was accessed, when, and whose data. Your breach counsel makes the notification calls on those facts.

Sometimes it is, and it is worth checking your scope document. In practice most MSP contracts cover devices, patching, and user support, and stop short of the disciplines on this page: EDR policy tuning, SIEM detection engineering, immutable backup with tested restores, a rehearsed IR playbook, and phishing simulation. Ask your provider for the date of your last restore test and your last tabletop; the answers tell you whether you are covered. We can run this program alongside an incumbent MSP with written swim lanes.
