In short

Ransomware attacks encrypt your files and demand payment for the decryption key. To protect your SMB: keep all software patched and up to date, maintain offline backups that are tested monthly, deploy endpoint detection and response (EDR) software on every device, train staff to recognise phishing emails, and document a recovery plan that includes contact details for your IT provider and insurers. Most ransomware enters through phishing emails or unpatched vulnerabilities, so these five controls address the most common entry points. If you are hit, isolate infected machines immediately, do not pay the ransom, and restore from your most recent clean backup.

Ransomware attacks continue to disrupt Irish SMBs. In 2024, the average ransomware incident cost a small or medium business €220,000 when you account for downtime, lost revenue, recovery work and reputational damage. The Canadian Centre for Cyber Security's [Ransomware Threat Outlook 2025–2027](https://www.cyber.gc.ca/en/guidance/ransomware-threat-outlook-2025-2027) warns that attacks on SMBs are increasing because criminals see smaller organisations as easier targets with weaker defences and less mature incident-response plans.

Ransomware locks your files and systems until you pay a ransom. The attacker often enters through a phishing email or an unpatched software vulnerability, then spreads across your network, encrypts everything they can reach and leaves a ransom note. Some gangs now exfiltrate your data before encrypting it, threatening to publish sensitive information if you refuse to pay. Paying the ransom is no guarantee you will get your data back, and it funds further attacks.

This post shows how Irish SMBs can reduce the impact of ransomware with five practical controls: patching, offline backups, endpoint protection, staff training and a documented recovery plan. We draw on current threat intelligence and real-world incident data to explain what works.

## Why ransomware targets SMBs

Criminals target SMBs because they often lack dedicated security teams and run outdated software. [AAG's 2024 cyber crime statistics](https://aag-it.com/the-latest-cyber-crime-statistics/) show that 43 per cent of cyber attacks hit small businesses, yet only 14 per cent of those businesses feel prepared to defend themselves. The gap between threat and readiness makes SMBs attractive.

Ransomware gangs use automated tools to scan the internet for known vulnerabilities. If your server is running an unpatched version of Windows or your firewall has a default password, the attacker's script will find it. Once inside, the malware moves laterally across your network, looking for file shares, databases and backups to encrypt. The whole process can take hours. Many SMBs only discover the breach when staff arrive to find ransom notes on every screen.

The [SpyCloud 2024 Annual Identity Exposure Report](https://spycloud.com/blog/cybersecurity-industry-statistics-account-takeover-ransomware-data-breaches-bec-fraud/) found that 61 per cent of breaches involved stolen credentials. Attackers buy username and password combinations from data brokers, then use them to log in to your systems as if they were legitimate users. If you reuse passwords across services or fail to enforce multi-factor authentication, a single compromised credential can open your entire network.

## Keep all software patched and up to date

Unpatched software is the single largest entry point for ransomware. Microsoft, Adobe, Apple and every other vendor release security patches when they discover vulnerabilities. If you delay those updates, you leave the door open.

Run Windows Update, macOS Software Update and your Linux package manager every week. Enable automatic updates wherever possible. For line-of-business applications, check the vendor's support portal monthly and apply patches within 48 hours of release. Many ransomware strains exploit vulnerabilities that have been patched for months. The only reason they succeed is that the target never installed the update.

Firmware matters too. Routers, firewalls, network-attached storage devices and printers all run embedded software that needs patching. Log in to each device's admin console quarterly and check for firmware updates. If a device no longer receives updates from the manufacturer, replace it. An end-of-life firewall is a liability.

At Panoptic we manage patching for clients across [dental practices in Kilkenny](https://panoptic.ie/industries/dental), [veterinary clinics in Cork](https://panoptic.ie/industries/veterinary) and [accountancy firms](https://panoptic.ie/industries/accountants-solicitors) in both locations. We schedule updates during off-peak hours, test them in a staging environment first, and roll back if anything breaks. That discipline keeps ransomware out without disrupting daily work.

## Maintain offline backups that are tested monthly

Backups are your last line of defence. If ransomware encrypts your production data, a clean offline backup lets you restore everything without paying the ransom. The backup must be offline or air-gapped, meaning it is not connected to your network when it is not writing data. If the backup drive is mounted 24/7, the ransomware will encrypt it along with everything else.

Follow the 3-2-1 rule: three copies of your data, on two different media types, with one copy stored off-site. For example, keep one copy on your server, a second on a local NAS that disconnects after the backup job completes, and a third in a cloud service or a physically separate location. Test every backup monthly by restoring a sample file or folder and verifying its integrity. A backup you have never tested is a backup you cannot trust.

Automate the backup schedule so it runs every night. Use software that creates versioned snapshots, allowing you to roll back to a point in time before the infection. Retain at least 30 days of history. Some ransomware strains lie dormant for weeks before activating, so a single-day backup may already be compromised.

Document the restore procedure step by step. Include the software licence keys, admin passwords and contact details for your backup vendor. Store that document in a secure location outside your network, such as a password manager or a printed binder in a locked drawer. When ransomware hits, you will not have time to work out the restore process from scratch.

## Deploy endpoint detection and response (EDR) software on every device

Traditional antivirus software matches files against a database of known malware signatures. It catches old threats but misses new ones. Endpoint detection and response (EDR) software monitors behaviour in real time, looking for suspicious activity such as mass file encryption, unauthorised privilege escalation or connections to known command-and-control servers. When it detects an anomaly, it can quarantine the device, kill the malicious process and alert your IT team.

Install EDR on every laptop, desktop, server and mobile device. A single unprotected machine is enough for ransomware to gain a foothold. Configure the EDR agent to report to a central console so you can see alerts across your entire fleet. Many EDR platforms include automated response playbooks that isolate infected devices before the malware spreads.

Choose an EDR product that integrates with your existing infrastructure. [SentinelOne's guide to account takeover prevention](https://www.sentinelone.com/cybersecurity-101/threat-intelligence/the-ultimate-guide-to-preventing-account-takeover-attacks/) highlights the importance of correlating endpoint telemetry with identity logs. If an attacker uses stolen credentials to log in, the EDR can flag the unusual login location or time and trigger a multi-factor authentication challenge.

EDR is not a set-and-forget tool. Review the alerts weekly and tune the detection rules to reduce false positives. Train your IT team to investigate suspicious events and escalate confirmed incidents. If you lack in-house security expertise, consider a managed detection and response (MDR) service that monitors your endpoints 24/7 and responds to threats on your behalf.

## Train staff to recognise phishing emails

Most ransomware infections start with a phishing email. The attacker sends a message that looks like it comes from a trusted source (your bank, a delivery company, a colleague) and includes a malicious link or attachment. One click is all it takes.

Run quarterly phishing simulations. Send fake phishing emails to your staff and track who clicks the link or downloads the attachment. Those who fall for the simulation receive immediate feedback and targeted training. Repeat the exercise every three months with different lures: invoice scams, password-reset requests, fake meeting invites. The goal is to build a reflex that makes staff pause and verify before clicking.

Teach staff the warning signs: generic greetings ("Dear Customer"), urgent language ("Your account will be locked"), misspelled domains (micros0ft.com instead of microsoft.com), unexpected attachments. Encourage them to hover over links to see the real URL before clicking. If an email looks suspicious, they should forward it to your IT team for analysis rather than risk opening it.

Make reporting easy. Set up a dedicated email address (phishing\@yourcompany.ie) where staff can forward suspect messages. Acknowledge every report and provide feedback within 24 hours. Staff who report phishing attempts should be thanked, not criticised. A culture of vigilance is your best defence.

The [Huntress blog on account takeover](https://www.huntress.com/blog/account-takeover-what-it-is-and-how-to-protect-against-it) notes that 91 per cent of cyber attacks begin with a phishing email. Training your staff cuts that attack surface dramatically.

## Document a recovery plan that includes contact details

A recovery plan turns chaos into a checklist. When ransomware hits, you need to know exactly who to call, which systems to isolate and how to restore from backup. Write the plan now, before an incident, and store it somewhere your team can access even if the network is down.

Your recovery plan should include:

- Contact details for your IT provider, cyber insurers, legal advisors and the Garda National Cyber Crime Bureau.
- A list of critical systems in priority order: which servers, applications and data must be restored first.
- Step-by-step instructions for isolating infected devices, including how to disconnect them from the network without shutting them down (shutting down can destroy forensic evidence).
- The location of your offline backups and the credentials needed to access them.
- A communication template for notifying customers, suppliers and regulators if personal data is compromised.

Test the plan annually with a tabletop exercise. Gather your management team, present a ransomware scenario and walk through the recovery steps. Identify gaps, update the plan and train new staff. A plan that sits in a drawer is worthless.

If you are hit, do not pay the ransom. The [Canadian Centre for Cyber Security's ransomware outlook](https://www.cyber.gc.ca/en/guidance/ransomware-threat-outlook-2025-2027) advises that paying does not guarantee decryption and often marks you as a willing payer, inviting repeat attacks. Instead, isolate the infected systems, restore from your most recent clean backup and engage a forensic specialist to determine how the attacker got in. Fix that entry point before you bring systems back online.

## Common ransomware entry points and how to close them

[CyberDegrees' overview of common cyber attacks](https://www.cyberdegrees.org/resources/most-common-cyber-attacks/) identifies the most frequent ransomware vectors: phishing emails, remote desktop protocol (RDP) exploits, unpatched software and stolen credentials. Each vector has a straightforward mitigation.

**Phishing emails.** Deploy email filtering that blocks known malicious domains and quarantines suspicious attachments. Train staff as described above. Enable multi-factor authentication so that even if a user clicks a phishing link and enters their password, the attacker cannot log in without the second factor.

**RDP exploits.** If you expose RDP to the internet, attackers will find it and brute-force the password. Disable RDP on internet-facing systems or place it behind a virtual private network (VPN) that requires authentication before the RDP port is even visible. Use strong, unique passwords and limit RDP access to specific IP addresses.

**Unpatched software.** Automate patching as described earlier. Subscribe to vendor security bulletins so you know when critical updates are released. Prioritise patches for internet-facing services such as web servers, email gateways and VPN appliances.

**Stolen credentials.** Enforce multi-factor authentication on every account, especially admin accounts and remote-access tools. Use a password manager to generate unique passwords for each service. Monitor for compromised credentials on the dark web. Services such as Have I Been Pwned alert you when your email addresses appear in a breach.

What should I do immediately if I suspect a ransomware attack?

Isolate the infected device by disconnecting it from the network. Unplug the Ethernet cable or turn off Wi-Fi, but do not shut it down, as that can destroy forensic evidence. Notify your IT provider and cyber insurers immediately. Do not attempt to decrypt files yourself or pay the ransom before consulting experts.

How often should I test my backups?

Test backups monthly by restoring a sample file or folder and verifying its integrity. Run a full disaster-recovery test (restoring an entire server or workstation) at least once a quarter. Document the restore time so you know how long recovery will take in a real incident.

Is paying the ransom ever the right choice?

Paying the ransom does not guarantee you will receive a working decryption key, and it funds further criminal activity. Law enforcement and cybersecurity experts advise against payment. Instead, restore from your offline backups and fix the vulnerability the attacker exploited.

What is the difference between antivirus and EDR?

Antivirus software matches files against a database of known malware signatures. EDR monitors system behaviour in real time, detecting suspicious activity such as mass file encryption or unauthorised privilege escalation. EDR catches new, unknown threats that antivirus misses and provides detailed forensic data for incident response.

Do I need cyber insurance if I have good backups?

Yes. Cyber insurance covers costs beyond data restoration, including legal fees, regulatory fines, customer notification, public relations and business interruption. Many policies also provide access to incident-response specialists who guide you through the recovery process. Backups and insurance are complementary, not alternatives.

How do I know if my software is up to date?

Enable automatic updates wherever possible. For Windows, run Windows Update weekly. For macOS, check Software Update in System Preferences. For line-of-business applications, log in to the vendor's support portal and check for patches monthly. Keep a spreadsheet of all software in use, the version installed and the date you last checked it, so nothing slips through unpatched.
