DDoS Protection for VPN Gateways
Remote workers depend on VPN gateways. Protecting them keeps the workforce connected.
For many organisations, VPN gateways are the doorway through which remote employees reach internal systems. If an attacker floods the gateway, the remote workforce is cut off — even if office systems are working perfectly.
Why VPN gateways are targets
They are internet-facing, their addresses are easy to discover and disrupting them causes widespread impact. Attacks may also aim to exhaust connection limits or authentication systems.
Network-level protection
DDoS mitigation in the provider's network protects the bandwidth leading to VPN gateways, filtering volumetric floods before they arrive.
Rate limiting and connection controls
Configure gateways to limit connection attempts per source and drop malformed traffic.
Strong authentication
Multi-factor authentication prevents attackers from abusing stolen credentials, and account lockout policies limit brute-force attempts.
Patch regularly
VPN gateways are frequent targets for vulnerability exploitation. Keep them updated.
Redundancy
Deploy multiple gateways in different locations or on different links so users can connect elsewhere if one is attacked.
Cloud-based access
Zero-trust access services hosted in the cloud distribute connectivity across many points of presence, reducing exposure.
Monitoring
Track connection counts, authentication failures and bandwidth to detect attacks early.
Communication plan
Prepare messages for employees explaining alternatives during disruptions.
The bottom line
Protect VPN gateways with network-level DDoS mitigation, strong authentication and redundancy to keep your remote workforce connected.
