A practical, step-by-step guide to switching on multi-factor authentication in Microsoft 365 — covering Security Defaults, Conditional Access, and the mistakes to avoid.
Read moreIf your business uses Microsoft 365, you already have one of the world’s most secure cloud platforms, but here’s the catch: many of its best defences are quietly turned off until you switch them on. Learn how to use five underrated Microsoft 365 security settings. Most small and medium-sized businesses assume Microsoft 365 is “secure by default,” in reality, the default configuration is designed for convenience, not complete protection. That means the security tools you’re already paying for might not...
Read moreRansomware attacks are no longer an “if” but “when,” the impact of a successful attack can be devastating: downtime, lost data, reputational harm, and financial damage. The best defence is preparation and a ransomware recovery playbook gives your business a clear, tested plan for what to do when the worst happens. At Commercial Networks, we help SMBs strengthen business continuity planning and build practical recovery strategies that reduce risk and speed up recovery. Why You Need a Ransomware Recovery Playbook...
Read moreThe clock is ticking. By April 2026, the UK will implement measures aligned with the EU’s revised NIS2 directive, designed to strengthen cyber resilience across critical industries and their supply chains. For SMBs, this means new obligations around risk management, reporting, and governance. Falling short could lead to penalties, reputational damage, and loss of business. At Commercial Networks, we guide organisations through NIS2 compliance UK requirements, combining policy reviews, Managed IT Services, and staff training to ensure nothing is left...
Read moreThere was a time when cybercrime required skill, patience, and insider knowledge. Not anymore. Now, anyone with an internet connection can buy hacking tools, phishing kits, or ransomware on subscription and no experience is required. Welcome to the age of Cybercrime-as-a-Service. For small and medium-sized businesses (SMBs), this shift has changed the game, cybercriminals no longer need to write code or find victims manually, they can buy the tools, rent the infrastructure, and automate the attack. That means every business,...
Read moreEvery year, businesses invest more in security tools; firewalls, filters, and monitoring. Yet phishing remains the most successful cyberattack. Why? Because phishing isn’t about the technology, it’s about people. The psychology of phishing explains why staff still click in 2026, even when they “know better.” At Commercial Networks, we help SMBs tackle the human side of cyber risk with employee cyber awareness, phishing simulations, and managed defences that address both tech and behaviour. Psychology of Phishing: Why It Works Phishing...
Read morePhishing has always been one of the biggest risks to businesses, but it’s evolving at alarming speed, attackers are no longer relying on clumsy typos and obvious scams. Instead, they’re using artificial intelligence to create convincing emails, deepfake calls, and even automated campaigns. This new wave of AI-driven phishing means human vigilance alone is no longer enough. At Commercial Networks, we combine staff training with proactive Managed IT Services to keep our clients ahead of these smarter, faster attacks. Understanding...
Read moreCybercriminals don’t just use email anymore. Increasingly, they’re targeting people where they least expect it: their phones. Smishing and vishing, scams delivered by SMS (text) and voice calls, are rising fast in 2026, fuelled by cheap technology and AI tools that make fake messages and calls harder to spot. At Commercial Networks, we help SMBs protect staff against these social engineering attacks with mobile cyber security, awareness training, and strong policies. Smishing and Vishing: What They Are The National Cyber...
Read moreArtificial intelligence is powering innovation, but it’s also fuelling new risks. Among them is deepfake fraud, the use of AI-generated audio or video to impersonate trusted individuals. Once the stuff of science fiction, deepfakes are now a real and growing cyber threat and for SMBs, the stakes are high. A convincing fake CEO voice on the phone or a fraudulent video call could trick staff into transferring money or sharing sensitive data. At Commercial Networks, we help SMBs stay ahead...
Read moreRansomware used to be the domain of highly skilled hackers, today, anyone with bad intentions and a credit card can launch an attack. The rise of ransomware-as-a-service (RaaS) has turned ransomware into a thriving criminal business model, and SMBs are among the biggest targets. At Commercial Networks, we help SMBs strengthen SMB cyber security defences and recover quickly if ransomware strikes. Understanding why RaaS is booming is the first step in protecting against it. Ransomware-as-a-Service: What It Is Ransomware-as-a-service works...
Read moreIt’s easy to click “remind me later” when software updates pop up, after all, what’s the harm in waiting until tomorrow? But for many small and medium-sized businesses, that small delay can lead to a big problem. Cybercriminals thrive on delay, every day a system goes unpatched, the odds of a breach increase. In fact, many major cyberattacks in recent years, including ransomware outbreaks and data leaks, started with a single missed update. At Commercial Networks, we treat software updates...
Read moreTechnology has never been stronger; firewalls, multi-factor authentication, and cloud defences all help protect SMBs. Yet cybercriminals know that the easiest way into a network isn’t through the tech, it’s through the people using it. Weak employee cyber security habits continue to cause the majority of breaches, and in 2026, the problem hasn’t gone away. At Commercial Networks, we help SMBs build a stronger human firewall through cyber security awareness training, phishing simulations, and policies that actually stick. Employee Cyber...
