Small and mid-sized businesses often rely on resource-constrained IT teams to manage complex security environments. These teams often have limited staff and tight budgets, which makes implementing adequate protections challenging. However, by strategically adopting the right solutions, even lean teams can meaningfully improve security.
This guide covers five accessible tools to help small IT departments reduce risk:
1. Password Manager
With users juggling dozens of passwords, reuse and weak credentials leave doors open for attackers. A password manager provides a centralized solution for strong, unique passwords across all services. For best results, integrate the manager with an identity provider for single sign-on (SSO) and automated provisioning.
2. Multifactor Authentication
Advanced options like one-click multifactor authentication (MFA) further secure access while improving user experience.
MFA prevents unauthorized account access by requiring a second form of identity verification beyond just a password. This protects against compromised credentials. Popular options include SMS codes, push notifications, biometrics, hardware tokens, and time-based one-time passwords (TOTPs).
We recommend deploying MFA across all sensitive accounts, especially remote access services like VPNs.
3. DNS Filtering
Another best practice is utilizing a DNS filter to control which websites and domains users can access. You should also utilize blacklists to block known malicious sites involved in phishing, malware, and ransomware campaigns.
Filtering is automated via existing DNS server settings, requiring no client software. This prevents users from accidentally visiting dangerous links, reducing infection risks.
4. Endpoint Detection and Response
Endpoint detection and response (EDR) monitors devices for suspicious activities indicating intrusions. Advanced EDR tools combine malware prevention with centralized monitoring and automated response capabilities.
When ransomware or other threats are detected, built-in workflows isolate affected endpoints to prevent spread. EDR is critical for early threat visibility and rapid containment.
5. Extended Detection and Response
Extended detection and response (XDR) expands visibility beyond endpoints to include networks, cloud environments, and other systems. Correlating cross-system events provides a unified view of potential threats, and integrated incident response workflows let IT take action against threats detected anywhere in the environment. The Blumira XDR platform builds on EDR and SIEM technologies to unify security.
The Path Forward
Adopting even a subset of these five tools can significantly improve security posture. Start with high-impact solutions like MFA and DNS filtering to make rapid progress securing your organization. Prioritize affordable and streamlined options suitable for small IT teams.
With the right technology partners, resource-constrained businesses can build effective defenses against modern cyber threats.
