In 2026, SMEs must take a very tailored, targeted approach to preventing business cyberattacks. The key to carrying this out successfully is to adopt a customised strategy that addresses the most pressing cyber risks facing your organisation.
Going it alone can be daunting, which is why many business owners are now turning to expert managed service providers (MSPs) for practical guidance on preventing cyberattacks and protecting their company’s systems, data and operations.
In this article, we explore the steps involved in building such a protective framework and discuss how an IT partner can ensure your cybersecurity infrastructure is both comprehensive and robust.
Step #1: Review access, password and authentication protocols across all systems
One of the best places to start when protecting your systems against cyber threats is to review who has access and how secure the entry points are.
This involves implementing stringent measures across three main areas:
- Access Permissions: According to the principle of least privilege (PoLP), users should only have access to information that is relevant to their job. To adhere to this, it’s vital to remove or flag unnecessary access rights across folders, drives and tools
- Multi-Factor Authentication: Multi-factor authentication (MFA) is designed to prohibit unauthorised access to confidential information by seeking multiple verification methods. It should be implemented across Microsoft 365, email, VPN and any systems that provide access to sensitive data
- Password managers: Password managers serve several functions. Aside from providing a safe space for password storage, they can also automatically generate highly secure passwords, which reduces the risk of system breaches
Step #2: Regularly update and verify software and security tools
Old or outdated software often serves as an entry point for hackers attempting to infiltrate a business’s network. Therefore, carrying out regular updates across systems and applications is crucial for security-conscious SMEs.
Enabling auto-updates is a good place to start. It’s also hugely important to make employees aware of the importance of manually checking and acting upon any update notifications.
Security tools, such as firewalls and email filtering, should ideally be applied in tandem with regular patch updates to further strengthen defences against attackers preying on system vulnerabilities.
However, don’t just take for granted that these protective tools are working seamlessly in the background; security icons and task status dashboards should be checked and verified regularly to ensure they are functioning properly.
Step #3: Preventing business cyberattacks through regular employee training
In Ireland at present, 52% of companies are experiencing a three-to-six-month delay in filling entry-level cybersecurity roles. This is hugely problematic for SMEs relying heavily on AI tools to run their businesses both cost-effectively and efficiently.
To combat this issue and to mitigate the lingering risk of human error, business owners need to coordinate regular employee cybersecurity awareness training with a trusted IT provider.
The main goal with this is to ensure teams are consistently up to speed on the latest cyber threats and the actions they must take to avoid falling prey to potential attacks.
Comprehensive training should include phishing simulations to build muscle memory, training on proper inspection and verification practices, and guidance on how to report suspicious activity.
Step #4: Implement reliable backup and disaster recovery solutions
To avoid the financial and reputational repercussions of downtime, proactive backup and disaster recovery planning are a must.
An effective plan should include the following procedures:
- Implement the 3-2-1 rule for backing up sensitive data: have three copies, on two different media, with one located off-site
- Safeguard cloud-based data by utilising features like encryption, 24-hour monitoring and automatic backups
- Implement methodologies for rapid disaster recovery to facilitate minimal downtime
Through a range of managed solutions, an experienced IT partner will be perfectly positioned to craft a customised backup and disaster recovery plan to suit the risk profile of any SME, eliminating panic and providing valuable peace of mind.
Step #5: Secure remote working environments
In 2025, it was revealed that Ireland ranked highest across Europe for the availability of remote jobs. While this flexibility brings undeniable benefits to employees, it also brings risks, from a cybersecurity point of view, that require careful consideration.
To ensure remote access methods are secured and that compliance with company policies is strictly adhered to regardless of location, a range of measures should be implemented. These involve:
- Prioritising a Zero Trust approach
- Establishing MFA for all email accounts, VPNs and more
- Stipulating the use of password managers
- Utilising Mobile Device Management software when BYOD policies are in place
When cybersecurity becomes a consistent focus, remote teams and employers alike can continue to safely enjoy the many advantages of this flexible work model.
Step #6: Develop a thorough incident response plan
Taking a proactive approach to cybersecurity is a proven way to mitigate cyberattacks, particularly in an era when AI is creating a wider scope for exploitation.
A true test of proactivity lies in the creation of a thorough incident response plan.
A comprehensive plan should detail:
- Step-by-step information on how to respond to an incident
- Who is responsible for each action
- How compromised systems will be contained
- Protocols for effective disaster recovery and data retrieval
This plan should be ready to roll out in the event of an attack, with all teams briefed and prepared to respond should the need arise.
