Increased complexity in API security is creating vulnerabilities and loss of control
How Cloudflare helps teams improve API security
Address shadow APIs
Cloudflare enables IT and Security leaders to gain visibility over their public APIs, schemas and performance metrics.
Positive API security model
Protect APIs by only accepting traffic that conforms to your OpenAPI schemas. Block malformed requests and HTTP anomalies.
Stop OWASP attacks
Block OWASP API Top 10 attacks including authentication, data loss, abuse, DDoS and brute-force attacks.
Block API abuse
Stop volumetric and sequential API abuse of XML, RESTful and GraphQL APIs through simple heuristics and advanced anomaly detection.
Streamline API management
Centrally register and manage endpoints discovered or added to the central API endpoint console.
API discovery
Discovery of API endpoints in use.
Mutual TLS
One button mTLS authentication support to block requests from illegitimate clients.
Sensitive data detection
Detect sensitive data leaving in API response phase.
FEATURES
Key benefits of an integrated API security solution
Discover and catalog all of your APIs
An organization’s or developer’s API inventory is captured through API schemas — the metadata that defines the specifications of a valid API request and response.
These API schemas (often documented with OpenAPI specifications) include the API host, HTTP method, path, and other requirements established by developers, such as path and query variables.
Monitor which APIs allow ‘write’ access
When aggregated across all account APIs, Cloudflare found that 59.2% of organizations permitted ‘write’ access to at least half of their APIs.
When an API provides ‘write’ access to the wrong person, it can lead to attacks such as those described in this report.
Assess and monitor API errors and trends
Understanding the root cause of API errors (and the trends behind those issues) requires consistent logging of API traffic, and analyzing trends over time.
Do you know how much of your API traffic is rate limited? How much of it is forbidden (due to bad authorization)?
API Security: Assess your risk exposure
APIs are crucial for modern businesses, but vulnerable endpoints pose significant risks for data exposure and compliance failures. This guide helps you assess your specific API risks with a step-by-step framework for identifying threats and developing a targeted remediation strategy.
What our customers are saying
"We wanted a security layer that could protect our web properties and APIs without adding significant overhead."
