• Tools: Snort, Suricata, IBM QRadar.

3. Virtual Private Networks (VPNs)

VPNs encrypt data transmitted over the internet, ensuring secure remote access to the network.

• Top VPN Solutions: NordLayer, Cisco AnyConnect, OpenVPN.

4. Endpoint Protection Platforms (EPP)

EPP tools secure individual endpoints like laptops and smartphones against threats like malware and ransomware.

• Leading EPPs: CrowdStrike Falcon, McAfee Endpoint Security, Symantec Endpoint Protection.

5. Network Access Control (NAC) Solutions

NAC tools enforce policies to ensure that only authorized and compliant devices connect to the network.

• Popular NAC Tools: Cisco ISE, Aruba ClearPass, Forescout.

6. Multi-Factor Authentication (MFA)

MFA adds an additional layer of security by requiring multiple verification methods to access the network.

• Solutions: Duo Security, Microsoft Authenticator, Okta.

7. Security Information and Event Management (SIEM)

SIEM systems aggregate and analyze security data to detect anomalies and provide alerts.

• Top SIEM Tools: Splunk, SolarWinds Security Event Manager, LogRhythm.

8. Data Loss Prevention (DLP) Tools

DLP tools prevent unauthorized access to sensitive data and ensure compliance with data protection regulations.

• Best DLP Solutions: Forcepoint, Symantec DLP, Digital Guardian.

9. Wireless Intrusion Prevention Systems (WIPS)

WIPS solutions secure wireless networks by identifying and mitigating unauthorized access points or rogue devices.

• Leading WIPS Tools: Aruba WIPS, Cisco Meraki Air Marshal.

10. Email Security Solutions

Email gateways prevent phishing, malware, and spam from reaching employees.

• Top Tools: Mimecast, Proofpoint, Barracuda Email Security Gateway.

11. Cloud Access Security Brokers (CASB)

CASB tools protect cloud-based resources by enforcing security policies and monitoring user activity.

• Popular CASBs: Netskope, McAfee MVISION Cloud, Microsoft Defender for Cloud Apps.

12. Vulnerability Scanners

These tools identify weaknesses in network infrastructure and applications.

• Best Scanners: Nessus, Qualys, OpenVAS.

13. Secure DNS Services

Secure DNS solutions block malicious domains to prevent phishing and malware attacks.

• Top Services: Cisco Umbrella, Cloudflare Gateway, Quad9.

14. Encryption Tools

Encryption tools ensure that sensitive data is accessible only to authorized users.

• Recommended Tools: VeraCrypt, BitLocker, AxCrypt.

15. Patch Management Tools
