Web Application Firewall
Protect web applications without complexity
Modern WAF protection that shields internal and external apps with Zero Trust controls and clean operations. Keep services online, stop common exploits, and stay audit ready.
- Block OWASP Top 10 patterns
- No heavy appliances or rework
- Central policies and visibility
What is Web Application Firewall (WAF)?
A Web Application Firewall inspects and filters HTTP traffic to protect applications against exploitation. Jimber WAF applies rule sets and behavioral checks to block injection, XSS, and other web attacks before they reach your code. It fits cloud and on-prem apps, aligns with Zero Trust access, and gives operations teams central visibility for faster incident response and easier compliance across European requirements.
Inspect
Parse requests and responses at the application layer to spot threats.
Enforce
Apply rules and behavior checks, then block or challenge risky traffic.
Observe
Log events and metrics for audits and response.
How WAF works
Why you should choose Web Application Firewall
- Fewer exploit attempts reach origin services
- Consistent policies across sites and tenants
- Faster incident triage with central logs
- Safer external and internal app exposure
- Rollouts without service downtime
Key Capabilities
- Threat detection
- Injection protection: Detect and block SQL and command injection.
- XSS filtering: Strip and deny malicious scripts in inputs and payloads.
- Control & Policy
- Positive and negative security: Allow-lists and signature rules per app.
- Bot and abuse controls: Rate limits and challenge flows for scrapers.
- Operations
- Central logging: Unified events for audits and response.
- Per-tenant policies: Multi-tenant model for MSPs and groups.
- Platform Fit
- API-first control: Manage rules, exceptions, and exports via API.
- Flexible deployment: Protect public and internal apps across sites.
Why Jimber for WAF
- Simple rollout and operations in one cloud managed console.
- Zero Trust by default when combined with identity and device posture.
- Partner-first multi-tenant model for MSP efficiency and margins.
- Reliable European platform aligned with GDPR and NIS2 expectations.

FAQs about Web Application Firewall
What is the difference between WAF and VPN?
A WAF protects web apps by filtering HTTP traffic. A VPN creates a network tunnel. Use WAF to stop web exploits and ZTNA or VPN for transport access control.
How does WAF enforce Zero Trust?
Pair WAF with identity and ZTNA so only verified users reach protected routes. The WAF then inspects requests per policy for least-privilege access.
What is the impact on latency and performance?
Inspection adds minimal overhead. Policies and caching are tuned to keep responses fast while blocking malicious requests.
Can I deploy this in OT networks?
Yes. Place WAF in front of internal dashboards and HMIs. Use NIAC to bridge agentless devices and restrict exposure to verified users only.
What telemetry is collected?
Security events, request metadata, rule matches, and actions taken. Payload elements are logged only as defined by your policy with retention you control.
Do I need new circuits?
Start in monitor mode, add exceptions where needed, then move to block. Versioned rules and per-app policies limit blast radius.
