A Web Application Firewall (WAF) filters HTTP and HTTPS traffic before it reaches your web application. It blocks suspicious requests linked to SQL injection, cross-site scripting, and malicious bots. But WAF rules aren’t foolproof. Legitimate requests can get blocked, attackers…
A Web Application Firewall (WAF) protects web applications and APIs by filtering HTTP/HTTPS traffic and blocking suspicious requests before they reach application servers. But filtering traffic alone won’t stop every attack. The OWASP Top 10:2021 ranks Broken Access Control as…
Zero trust network access ZTNA vs VPN comes down to how much access users need and how organizations manage risk. ZTNA limits access to approved applications, while a VPN can connect users to wider network resources. NIST published its zero…
Performance considerations VPN encryption overhead includes more than the encryption algorithm itself. VPN encryption overhead can slow connections by increasing CPU use, packet size, and processing time. WireGuard is generally efficient, but a speed loss of 50% or more may…
Securing VPN endpoints MFA strong authentication helps protect remote access from stolen credentials, phishing, and compromised devices. However, adding MFA alone won’t stop every attack. A trusted account can still connect through an infected laptop or access systems it doesn’t…
Detecting anomalous VPN connection behavior means finding connections that differ from a user’s usual login times, devices, locations, networks, or activity after login. These changes can point to stolen credentials, unauthorized access, or normal work changes that need verification. At…
Monitoring VPN user activity logs audits helps organizations track remote access, identify suspicious behavior, and check whether security controls work as expected. We get a clearer picture when VPN connection records are matched with identity, endpoint, and application logs. This…
VPN concentrator high availability redundancy should keep the VPN reachable and recover sessions when the active concentrator or its network path fails. The design goes beyond shifting a virtual IP to a standby device. IPsec tunnels, NAT states, routes, and…
Split tunneling VPN risks configuration options depend on which traffic stays inside the encrypted tunnel and which traffic uses the direct internet connection. The setup can reduce VPN congestion and improve performance, but it can also reduce visibility and expose…
Remote access VPN client security best practices start with strong authentication, trusted devices, secure routing, and limited access. MFA, certificate-based authentication, endpoint checks, and least-privilege rules can reduce common risks, but they work best as part of one security approach. …
