Managed EDR for Small Business vs Antivirus

Most small organizations bought antivirus once, renewed it quietly for a decade, and assumed endpoint security was handled. Then someone clicked a link in a convincing invoice email, credentials walked out the door, and the clean scan report from Friday meant nothing by Monday morning.

That gap is the whole case for managed EDR for small business: endpoint detection and response, watched by people, with a tested recovery path attached to it. Below is what behavior-based detection catches that signature-based antivirus does not, where Acronis fits, and the questions worth asking any provider — including us.

Does EDR replace antivirus for small business?

In many modern stacks, yes. Many EDR platforms include the malware scanning that standalone antivirus provided and add continuous behavioral telemetry on top of it. In those cases you are not running both products; you are replacing a category that was designed around a narrower threat model. Whether that holds for your environment depends on the specific platform, so check before you cancel anything.

The difference in practice:

	Traditional antivirus	EDR
Primary method	Signatures and known-bad file hashes	Process behavior, parent-child relationships, memory activity
Catches	Known malware files on disk	Living-off-the-land tooling, credential theft, script abuse, lateral movement
Output	Blocked / not blocked	Alert with attack chain context
Response	Quarantine the file	Isolate the device and kill the process chain; some platforms add rollback
Who acts on it	Often no one	A SOC analyst, if you have one

That last row is where most SMB deployments fall over. EDR generates investigative signal. Signal nobody reads is just storage.

What does behavior-based detection actually catch?

It catches the intrusions that never involve a malicious file at all. Acronis reports that in H2 2025, email attacks rose 16% per organization and 20% per user, with phishing accounting for 83% of all email threats — telemetry Acronis says is drawn from over one million global endpoints.

A stolen password used to sign in during business hours does not look like malware. It looks like an employee. Signature matching has nothing to compare it against. Behavioral detection looks at what happens next: the unusual process spawning PowerShell, the sudden enumeration of file shares, the encryption routine touching hundreds of documents a minute.

That shift matters because credential-driven intrusion is growing as a share of the problem. In its earlier Cyberthreats Report H1 2025, Acronis measured social engineering and business email compromise rising from 20% to 25.6% of attacks between January–May 2024 and the same period in 2025.

Acronis also reports that 80% of ransomware-as-a-service vendors now advertise AI or automation features to their criminal customers, which mostly means the volume and polish of what lands in an inbox keeps improving.

One caveat on all of the above: these are vendor-produced figures from Acronis’s own sensor network. The email and RaaS numbers come from the Acronis Cyberthreats Report H2 2025 (February 18, 2026); the social engineering figure comes from the H1 2025 edition (August 20, 2025). Read them as Acronis telemetry, not independent industry consensus.

Are small organizations actually targeted?

More often than the “nobody wants our data” assumption suggests. Expert Insights’ compilation puts ransomware experience at 47% of organizations with 100–1,000 employees, compared with 54% of organizations with 1,001–5,000 — a much narrower gap than most owners expect.

For scale, Acronis documented over 7,600 publicly disclosed ransomware victims globally in H2 2025, with Qilin, Akira and Cl0p the most active groups. Those counts come from public leak-site postings, so they undercount unreported incidents rather than overstate the problem. Acronis separately reported a 70% increase in global ransomware victim counts in its H1 2025 report.

What is the difference between EDR and XDR?

EDR watches endpoints. XDR correlates endpoint signal with other sources — email, identity, cloud workloads — so one weak indicator in three places becomes one credible alert instead of three ignored ones.

For a 40-person business, that distinction matters less than whether anyone is triaging the alerts. For a district with 3,000 devices and a Microsoft 365 tenant, it matters a lot.

Acronis states that Acronis XDR earned SE Labs’ highest AAA certification in the June 2025 Advanced Security Test for EDR, with 100% Detection Accuracy and 98% Total Accuracy. Treat that as what it is: a point-in-time test of a specific product version under a specific configuration. No deployment reproduces a lab result, and we do not promise one.

Does Acronis Cyber Protect Cloud include EDR?

Treat it as a licensing question, not an assumption. Acronis positions Cyber Protect Cloud as backup and recovery combined with security in a single agent and single console. Whether EDR is active in your tenant depends on what your subscription includes — so confirm that with us before you budget per device on the assumption it is already covered.

On third-party testing, Acronis states that Cyber Protect Cloud received AV-TEST Top Product Awards in multiple 2025 evaluations and achieved a 100% protection rate in AV-TEST’s real-world Advanced Threat Protection evaluation, and that Info-Tech named it an XDR Champion and named Acronis a Champion in backup and availability. Those are Acronis’s claims about Acronis’s testing results, cited as such — and like the SE Labs result, they are point-in-time evaluations of specific versions and configurations. No production deployment should be sold on the expectation of reproducing them.

palmiq is an Acronis Platinum partner, in the top 1% globally. We also partner with CrowdStrike and SentinelOne, which play in the same space. Which one we recommend depends on your requirements — existing tooling, compliance scope, in-house capacity — not on a belief that one agent wins every environment.

Can EDR recover files after ransomware encrypts them?

Some platforms can, and this is the leg most endpoint programs are missing. Detection without recovery is half a security program: the alert fired, the analyst responded, and the business still lost two days because restore lived in a separate system nobody had tested.

The reason we anchor a lot of SMB work on Acronis is that detection, response and image-level recovery share one agent. When an incident is contained, rolling the endpoint back to a known-good state is a step in the same console rather than a different vendor, a different credential, and a hopeful phone call.

That does not make recovery automatic. It makes it testable — which is the only version of recovery worth counting on.

Do I still need EDR if I have Microsoft Defender?

Usually the gap is not the tool, it is the operations around it — and the second gap is knowing which Defender you actually own. Microsoft sells endpoint protection under the Defender name across more than one plan, with different feature sets, and what your subscription entitles you to depends on your current licensing. Confirm it against Microsoft’s own documentation before assuming coverage.

What no license includes is somebody reading the alert at 2 a.m., deciding whether to isolate the machine, and starting recovery.

That is the part palmiq staffs: a 24/7 SOC with a 15-minute response SLA on critical issues. Across our MDR and EDR services we run a 99.9% threat neutralization rate and neutralize 1,200+ threats monthly.

Does CMMC Level 2 require endpoint detection and response?

CMMC Level 2 assessments evaluate an organization against NIST SP 800-171, and malicious code protection, system monitoring, incident response and system recovery are all control areas an assessor will look at. Endpoint tooling supports those controls. It does not deliver them.

Be skeptical of any vendor that says otherwise. Products support controls; assessments certify organizations. Before selecting a cloud-backed endpoint or backup tool for an environment with CUI, confirm the current 800-171 revision your contracts invoke, your DFARS 7012 flow-down obligations, and where data actually resides. Our GCC High work sits with Microsoft workloads, which is where our Microsoft partnership applies.

What about unmanaged and BYOD devices?

They are where coverage quietly stops. NordLayer’s 2025 roundup reports that 30% of machines appearing in credential-stealer logs are enterprise-licensed, and 46% are unmanaged devices mixing work and personal credentials.

For K-12 1:1 fleets, nonprofit volunteer laptops and hybrid staff using personal machines, partial enrollment is the actual risk. An agent on 80% of devices tells you a great deal about 80% of your environment.

What should an SMB look for in a managed endpoint security provider?

Ask about their security, not just yours. Acronis reported nearly 150 MSP and telecom organizations were directly targeted in H2 2025, which makes your provider part of your attack surface.

Reasonable questions:

• Is MFA enforced on every administrative and RMM account, without exception?
• How are client tenants separated, and who can cross between them?
• Who responds at 3 a.m., and what is the contracted response time?
• When was the last restore test, and can you see the results?
• Is recovery included in the endpoint program, or billed as a separate project when you need it most?

If a provider cannot answer the restore-test question with a date, the detection story is incomplete.
