5 Common Cybersecurity Mistakes Your Business Might Be Making Right Now

In today’s hyperconnected world, cybersecurity isn’t just an IT concern—it’s a business-critical priority. Yet even the most well-intentioned organizations leave the door open to threats through simple, avoidable mistakes. From compromised credentials to overlooked updates, these vulnerabilities can cost businesses time, money, and reputation.

Here are five common cybersecurity missteps your company may be making right now—and what you can do to correct them before they lead to a breach.

1. Reusing or Poorly Managing Passwords Across Teams

Credential reuse is one of the leading causes of business account takeovers. Many organisations still allow shared logins or weak, reused passwords across departments—especially for SaaS tools and cloud platforms.

Business Risk: A breach of one account can cascade across systems, exposing sensitive data and IP.

What to Do: Enforce strong, unique passwords for all users and implement enterprise-grade password managers like Password Business or LastPass Teams. Where possible, deploy multi-factor authentication (MFA) across all systems.

2. Delaying Critical Software and Security Updates

Busy teams often push back software updates or patch cycles—especially for non-customer-facing systems. But every delay increases your exposure to known vulnerabilities.

Business Risk: Unpatched software is a prime target for ransomware and exploit-based attacks.

What to Do: Develop a formal patch management policy with strict timelines. Automate updates when possible and maintain a clear inventory of all devices, operating systems, and software versions in use.

3. Underestimating Phishing Threats to Employees

Even tech-savvy employees fall for sophisticated phishing emails—especially those impersonating executives, vendors, or trusted platforms.

Business Risk: Phishing remains the top vector for credential theft, business email compromise (BEC), and malware infections.

What to Do: Run regular phishing simulations and offer mandatory cybersecurity awareness training. Reinforce a “verify-before-you-click” culture and implement email filtering solutions that detect and flag suspicious content.

4. Using Unsecured Networks or Devices for Work

With remote and hybrid work now the norm, many employees access corporate resources from home networks or personal devices without proper security protocols.

Business Risk: Sensitive business data can be intercepted or exposed on unsecured networks or unmonitored endpoints.

What to Do: Deploy a VPN for remote access, enforce device encryption, and implement mobile device management (MDM) to monitor and secure BYOD usage.

5. Assuming Cybersecurity Is IT’s Responsibility Alone

One of the most dangerous assumptions in B2B environments is that cybersecurity is solely the domain of IT. In reality, every employee plays a role in protecting company data.

Business Risk: Lack of cross-functional ownership leads to gaps in policy enforcement, awareness, and response readiness.

What to Do: Make cybersecurity a company-wide priority, with leadership buy-in and cross-department collaboration. Align security goals with business objectives, and ensure that everyone—from finance to marketing—understands their role in keeping the organization secure.

Final Thought

Cybersecurity threats evolve daily—but so can your defenses. By addressing these five common mistakes proactively, your business can significantly reduce its risk profile and build a more resilient digital infrastructure.
