Request inspection
Managed WAF
Inspect URI, headers, query strings, cookies, and request bodies before traffic is forwarded to your application.
Website Protection
A smarter edge between every request and your origin.
Proxy web traffic through NorthShield to inspect requests before they reach your origin. Apply managed WAF rules, rate limits, bot controls, JavaScript Challenge, or CAPTCHA Challenge according to risk.

Request decision engine
Inspect first. Challenge when needed. Block with context.
Every request is evaluated against WAF policy, client behavior, route sensitivity, and request rate. The response can stay invisible to trusted visitors while suspicious traffic faces progressively stronger validation.

Protection controls
Layer 7 controls built around the application.
Combine managed filtering with route-specific policies instead of treating every visitor and endpoint the same.
Silent browser proof
JavaScript Challenge
Ask suspicious visitors to complete a lightweight browser check before a trusted session is allowed through.
Human verification
CAPTCHA Challenge
Escalate higher-risk requests to an interactive CAPTCHA when passive browser validation is not enough.
Automation defense
Bot controls
Separate useful automation from abusive crawlers, credential stuffing, scraping, and high-rate scripted traffic.
Endpoint protection
Rate limiting
Apply targeted request limits to login, search, checkout, API, and other resource-intensive routes.
Protected upstream
Origin shielding
Keep the origin outside the public request path and accept application traffic through the protected edge.
Adaptive response
From transparent access to human verification.
Challenge strength follows risk. Trusted sessions continue, suspicious browsers prove they can execute JavaScript, and higher-risk visitors complete a CAPTCHA.
01Low risk
Allow
Known-good traffic continues
Requests that match your trusted policy proceed to the origin without an interactive step.
02Elevated risk
JS Challenge
Validate the browser silently
Suspicious clients must execute JavaScript and establish a valid browser session before continuing.
03High risk
CAPTCHA Challenge
Require human verification
High-risk sessions receive an explicit CAPTCHA Challenge before access to the application is granted.
04Malicious
Block
Stop hostile requests at the edge
Confirmed attack traffic is rejected before it consumes application or origin resources.
Threat coverage
Protect the application from exploits, bots, and request floods.
Build policies around the threats that consume origin capacity, abuse accounts, expose data, or interrupt customer journeys.
Application exploits
- SQL injection patterns
- Cross-site scripting
- Path traversal
- Protocol and header anomalies
Abusive automation
- Credential stuffing
- Aggressive scraping
- Fake account creation
- Inventory and checkout abuse
Layer 7 floods
- HTTP request floods
- Expensive endpoint abuse
- API burst traffic
- Slow and malformed requests
Deployment
Move into enforcement without guessing.
Start with application mapping and observation, then tighten policy around real production behavior.
Map
Identify domains, APIs, origin addresses, sensitive routes, and expected traffic patterns.
Proxy
Place NorthShield in the request path and restrict direct access to the protected origin.
Tune
Observe legitimate traffic, refine managed rules, and define challenge and rate-limit policies.
Enforce
Enable blocking with clear exceptions, monitoring, and an escalation path for production traffic.
Put NorthShield in front of your website and APIs.
Share your domains, origin architecture, sensitive endpoints, and traffic profile. We will design the WAF, JS Challenge, CAPTCHA Challenge, and rate-limit policy around your application.
