API attacks are up. WAF bypass techniques are documented on GitHub. And your perimeter is now a distributed mess of microservices, third-party APIs, and mobile endpoints. The old model of "put a WAF in front of it" barely holds up when your attack surface changes every sprint.
Cloud WAAP (Web Application and API Protection) tools have evolved to meet this reality. The best ones today combine traditional signature-based WAF rules with behavioral analytics, API discovery, and bot management in a single control plane. The worst ones still drown your team in false positives while missing actual OWASP Top 10 exploits because someone forgot to update a ruleset.
This roundup covers seven tools that sit in this space: Cloudflare WAF, Akamai App and API Protector, F5 BIG-IP Advanced WAF, Fortinet FortiWeb, Check Point CloudGuard WAF, Cisco WAAP, and Radware Cloud WAF Service. Each has a different deployment model, pricing posture, and sweet spot. We cut through the marketing to tell you what each one actually does well and where it falls short.

Cloudflare WAF sits inside Cloudflare's global anycast network, which means your traffic inspection happens at the edge, close to the user, before a single packet reaches your origin. That architecture gives it a latency advantage most on-premises or single-region cloud WAFs cannot match. It implements the OWASP Core Rule Set, adds machine learning detection on top, and layers in rate limiting and credential stuffing protection without requiring you to deploy anything new. If you already use Cloudflare for DNS or CDN, adding WAF is nearly frictionless.
What separates Cloudflare WAF from peers is the threat intelligence scale. The network processes a significant portion of global internet traffic, which means its ML models are trained on attack patterns that smaller vendors simply do not see. Zero-day exploit protection gets updated across the entire network simultaneously. You are not waiting for a signature push to a regional scrubbing center.
The ideal user here is any team that wants strong default protection without a dedicated WAF engineer. Startups and SMBs get enterprise-grade edge protection at a price point that makes sense. Mid-market and enterprise teams benefit from the custom rule engine and the ability to write Firewall Rules using Cloudflare's expression syntax, which is genuinely flexible. The file scanning and malware detection on uploads is a useful addition for any app that accepts user content.
The trade-off is lock-in. Cloudflare WAF is inseparable from the Cloudflare network. If your architecture requires on-premises inspection, hybrid deployment, or you have data residency requirements that conflict with Cloudflare's routing, this is not your tool. Custom rule logic is powerful but lives entirely in Cloudflare's platform. Portability is limited.
Akamai App & API Protector
Akamai App and API Protector is built for organizations that need protection at scale and cannot afford to babysit their WAF policy. The Adaptive Security Engine is the core differentiator: it learns attack patterns over time and self-tunes to reduce false positives without requiring manual intervention. For a SOC team that is already stretched, that matters. Most WAF deployments fail not because the tool is bad but because nobody has time to tune it. Akamai's self-tuning approach directly addresses that operational reality.
The hybrid deployment option, App and API Protector Hybrid, is worth calling out specifically. It extends Akamai's edge-based WAF protections to on-premises infrastructure, private clouds, and multi-CDN environments. This is a meaningful differentiator for enterprises that cannot route all traffic through a single CDN provider, or for regulated industries where some workloads must stay on-premises. The Behavioral DDoS Engine handles volumetric Layer 7 attacks at the edge, which keeps that traffic off your infrastructure entirely.
API discovery is built in, not bolted on. The platform can identify undocumented APIs in your environment, which is increasingly important as shadow APIs become a primary attack vector. The malware scanning module at the edge, combined with sensitive data protection, makes this a reasonable choice for e-commerce and financial services teams dealing with PCI DSS scope. DevOps integration via Terraform and CLI means security policy can live in version control alongside infrastructure code.
The gotcha with Akamai is cost and complexity. This is not a tool you spin up in an afternoon. Onboarding requires professional services engagement for most enterprise deployments. Pricing is not transparent and scales with traffic volume, which can produce billing surprises during traffic spikes or DDoS events. If you are an SMB without a dedicated security team, the operational overhead may outweigh the self-tuning benefits.
F5 BIG-IP Advanced WAF
F5 BIG-IP Advanced WAF is the tool you reach for when you need deep application-layer control and your environment is too complex for a pure cloud WAF. It supports GraphQL, REST/JSON, XML, and GWT API protocols natively, which matters when you are protecting a heterogeneous API estate that includes legacy SOAP services alongside modern REST endpoints. The behavioral analytics engine for Layer 7 DoS detection goes beyond simple rate limiting: it builds a baseline of normal application behavior and flags deviations, which catches slow-rate attacks that volumetric thresholds miss entirely.
The application-layer encryption feature is genuinely unusual. It encrypts sensitive form fields in the browser before data is transmitted, protecting against man-in-the-browser attacks and data-extracting malware that intercepts traffic before it is encrypted by TLS. This is relevant for financial services and healthcare applications where credential theft and session hijacking are primary threat vectors. Stolen credential protection with brute-force defense rounds out the identity-focused security posture.
Deployment flexibility is a real strength. BIG-IP Advanced WAF runs on dedicated hardware, hypervisors, private cloud, AWS, Azure, and GCP. The declarative API model means you can define WAF policy as code and push it through a CI/CD pipeline, which is how modern infrastructure teams expect to operate. SIEM, SOAR, and XDR integrations are documented and functional, not just listed on a datasheet.
The trade-off is operational complexity. F5 BIG-IP has a steep learning curve. The platform is powerful precisely because it exposes a lot of configuration surface, and that surface requires expertise to manage correctly. Misconfigured policies are a real risk. This tool fits mid-market and enterprise teams with dedicated application security engineers. If you are a three-person security team, the cognitive overhead will hurt you. Also note that hardware-based deployments carry significant capital cost.
Fortinet FortiWeb
FortiWeb's most distinctive characteristic is its dual-layer machine learning approach. The first layer detects anomalies against a statistical model of normal application behavior. The second layer validates those detections to reduce false positives before an alert or block action fires. In practice, this means fewer tickets for your developers to investigate and more confidence that what FortiWeb blocks is actually malicious. Most WAFs force you to choose between blocking mode with high false positives or detection mode with low confidence. FortiWeb's ML architecture tries to thread that needle.
The bot defense implementation is more sophisticated than most. Rather than relying solely on CAPTCHAs, which degrade user experience and are increasingly solvable by ML-based bots, FortiWeb uses biometric detection, bot deception techniques, and behavioral analysis to distinguish malicious bots from legitimate crawlers like Googlebot or uptime monitoring services. For e-commerce teams worried about credential stuffing, inventory scraping, and price manipulation bots, this granularity is operationally useful.
Client-side protection for payment pages is a direct response to Magecart-style attacks, where attackers inject malicious JavaScript into checkout flows to exfiltrate card data. FortiWeb monitors scripts running in the browser on payment pages, detects DOM manipulation and form hijacking, and addresses PCI DSS requirements for client-side security. This is a feature set that overlaps with dedicated client-side security tools, and having it integrated into the WAF reduces the number of agents and consoles you need to manage.
FortiWeb integrates tightly with the Fortinet Security Fabric, meaning FortiGate, FortiSandbox, and FortiGuard threat intelligence all feed into the same ecosystem. If you are already a Fortinet shop, this is a natural fit. If you are not, the integration story is less compelling. The hardware acceleration option for SSL/TLS offload is relevant for high-throughput environments where software-based inspection creates latency. Deployment is hybrid, covering on-premises hardware, virtual appliances, and cloud, which gives it flexibility that pure cloud WAFs lack.
Check Point CloudGuard WAF
Check Point CloudGuard WAF takes a different philosophical approach than most tools in this category. Where others layer ML on top of signature-based detection, CloudGuard WAF leads with contextual AI and machine learning as the primary detection mechanism, using signatures as a secondary layer. The stated goal is minimal false positives, which is a bold claim in a category where false positive rates are a chronic operational problem. The reverse proxy architecture means all HTTP/HTTPS traffic passes through the inspection engine before reaching the application, giving it full visibility into request and response payloads.
The deployment flexibility is genuinely useful for complex enterprise environments. Centralized deployments work for hub-and-spoke network models where traffic naturally flows through a single inspection point. Distributed deployments support decentralized architectures where applications are spread across multiple regions or cloud providers. Rule tuning via PowerShell and CLI, in addition to the dashboard, means security policy can be managed programmatically and integrated into infrastructure-as-code workflows without requiring a GUI.
API discovery is automated, which addresses the shadow API problem directly. Undocumented APIs are a persistent blind spot in most organizations, and having the WAF discover them through traffic analysis rather than requiring manual inventory is a practical advantage. The zero-day threat protection claim is backed by the contextual AI approach: because detection is behavior-based rather than signature-based, novel attack patterns that have no existing signature can still be caught if they deviate from normal application behavior.
The integration story is broad at a category level: SIEM systems, IPS, DDoS protection platforms, and CDNs are listed as integration targets. But the lack of named specific integrations in the database is worth noting. If you need a documented, tested integration with a specific SIEM like Splunk or a specific CDN, verify that before committing. CloudGuard WAF fits best in organizations already invested in the Check Point ecosystem, where centralized management across network and application security is a priority.
Cisco Web Application and API Protection (WAAP)
Cisco WAAP is a cloud-native solution that covers web applications, mobile applications, and APIs under a single protection umbrella. The mobile application protection angle is worth noting: most WAF tools focus exclusively on web traffic, but mobile API traffic has its own attack patterns, including certificate pinning bypass, API key extraction from mobile binaries, and mobile-specific bot behavior. Cisco's inclusion of mobile app protection in the core product reflects a more complete view of the modern application attack surface.
The machine learning and behavioral analysis engine continuously adapts security controls as the threat landscape changes, rather than requiring manual policy updates. For teams without a dedicated WAF engineer, this adaptive posture reduces the operational burden of keeping protection current. The platform monitors multiple applications simultaneously from a single control plane, which matters for organizations running dozens of web properties.
The 90-day free trial covering WAAP, bot protection, DDoS protection, and API protection for up to three applications is a practical way to evaluate the tool against real traffic before committing. That said, the trial requires contacting a sales representative to activate, which adds friction to the evaluation process. The 100 Mbps throughput cap on the trial is sufficient for most evaluation scenarios but will not reflect production performance for high-traffic applications.
The integration story is the weakest point in the available data. No specific integrations are listed, which makes it difficult to assess how well Cisco WAAP fits into an existing security stack. For organizations already running Cisco security infrastructure, the assumption is that integration is smoother, but that should be verified. This tool fits SMB to enterprise teams that want a cloud-delivered WAAP with minimal operational overhead and are comfortable with Cisco's support and licensing model.
Radware Cloud WAF Service
Radware Cloud WAF Service differentiates itself through its SecurePath architecture, which allows out-of-path deployment without requiring SSL certificate sharing or DNS routing changes. For security teams that have hit organizational resistance to routing all traffic through a third-party WAF provider, this is a meaningful architectural option. You get WAF protection without handing over your TLS private keys or changing your CDN configuration, which removes two of the most common objections to cloud WAF adoption.
The combination of a traditional negative security model with a behavioral-based positive security model gives Radware's approach more detection depth than tools that rely on one or the other. The negative model catches known attack signatures. The positive model learns what normal application behavior looks like and flags deviations. Cross-module correlation ties these signals together, which reduces the chance that a sophisticated attacker can evade detection by staying just below the threshold of any single detection mechanism.
Kubernetes support is explicitly called out, which is relevant for teams running containerized workloads. Many legacy WAF tools were designed for monolithic applications and struggle with the dynamic, ephemeral nature of Kubernetes environments where services scale up and down and IP addresses change constantly. Radware's support for Kubernetes deployments, alongside on-premises, public cloud, private cloud, and multi-cloud, gives it genuine deployment breadth.
The 24/7 managed security service through Radware's Emergency Response Team is a differentiator for organizations that want WAF protection but lack the internal expertise to respond to active attacks. This is particularly relevant for mid-market companies that have compliance requirements driving WAF adoption but do not have a SOC. The trade-off is that managed service models introduce a dependency on the vendor's response times and processes, which should be evaluated carefully in the contract.
How to Choose the Right Tool
Picking a cloud WAAP tool is not a features checklist exercise. Every vendor in this category claims OWASP Top 10 coverage, ML detection, and API protection. The real questions are about deployment fit, operational overhead, and what happens when you get a false positive at 2am. Here is what actually matters when you are making this decision.
Deployment architecture compatibility: Pure cloud WAFs like Cloudflare and Cisco WAAP require routing all traffic through the vendor's network. If you have data residency requirements, on-premises workloads, or multi-CDN architectures, you need a hybrid option like Akamai App and API Protector Hybrid, F5 BIG-IP Advanced WAF, or Radware's SecurePath out-of-path model. Verify that the deployment model works with your actual infrastructure before evaluating features.
False positive tolerance and tuning overhead: A WAF in blocking mode with high false positives is worse than no WAF. Ask vendors for false positive rates on real traffic, not lab benchmarks. Tools with self-tuning ML like Akamai and FortiWeb's dual-layer approach reduce manual tuning burden. If your team cannot dedicate time to policy tuning, prioritize tools with automated optimization.
API discovery and protection depth: If APIs are a significant part of your attack surface, check whether API discovery is active (traffic-based) or passive (schema import only). Active discovery catches shadow APIs. Also verify which API protocols are supported: GraphQL, REST, XML, and GWT have different attack surfaces, and not every WAF handles all of them equally well. F5 BIG-IP Advanced WAF has the broadest documented API protocol support in this group.
Bot management sophistication: Basic bot protection blocks known bad IP ranges and user agents. Sophisticated bot management uses behavioral analysis and biometric signals to catch bots that mimic human behavior. If credential stuffing, inventory scraping, or account takeover are in your threat model, evaluate the bot management capability specifically. Akamai and FortiWeb have the most detailed bot defense implementations in this roundup.
Integration with your existing security stack: A WAF that cannot send structured logs to your SIEM is a visibility gap. Check for documented integrations with your specific SIEM, SOAR, and ticketing tools. F5 BIG-IP Advanced WAF has the broadest named integration list here. Cloudflare integrates well with most log aggregation platforms. Cisco WAAP and Radware have the least specific integration documentation available.
Operational model: managed vs. self-managed: Some teams want to configure and own their WAF policy. Others want a vendor to manage it. Radware offers a 24/7 managed service with an Emergency Response Team. Akamai's self-tuning reduces management burden without full managed service. If you are a small team with compliance-driven WAF requirements, a managed service option may be the difference between effective protection and a misconfigured ruleset.
Ecosystem fit and vendor consolidation: If you are already running Fortinet infrastructure, FortiWeb's integration with FortiGate, FortiSandbox, and FortiGuard is a real operational advantage. If you are a Check Point shop, CloudGuard WAF fits naturally into your management plane. Vendor consolidation reduces console sprawl and can improve correlation across security events. Do not ignore this factor, but do not let it override a significant capability gap.
Total cost of ownership including traffic-based pricing: Several vendors in this category price on traffic volume, which means a DDoS event or a traffic spike can produce an unexpected bill. Understand the pricing model before you sign. Cloudflare's pricing is relatively transparent. Akamai's is not. For high-traffic applications, model out the cost at 2x and 5x your current traffic volume to avoid surprises.
Frequently Asked Questions
What is the difference between a WAF and a WAAP?
A WAF (Web Application Firewall) focuses on HTTP/HTTPS traffic inspection against known attack signatures and rules. A WAAP (Web Application and API Protection) extends that to include API security, bot management, and DDoS mitigation in a single platform. Most modern tools in this category are WAAPs even if they still use WAF in their product name.
Can a cloud WAF protect APIs, or do I need a separate API security tool?
Most tools in this roundup include API discovery and protection as part of the core product. The depth varies significantly: F5 BIG-IP Advanced WAF supports GraphQL, REST, XML, and GWT natively, while some others focus primarily on REST/JSON. For organizations with complex API estates including legacy SOAP services, verify specific protocol support before assuming coverage.
How do I reduce false positives without putting my WAF in detection-only mode?
Start with a learning period in detection mode to baseline normal traffic, then move to blocking mode with a narrow initial ruleset. Tools with automated self-tuning like Akamai App and API Protector or FortiWeb's dual-layer ML reduce the manual tuning burden significantly. Whitelisting known-good traffic patterns for specific endpoints is faster than trying to tune global rules.
Do I need to share my TLS private keys with a cloud WAF provider?
Most cloud WAFs that operate as reverse proxies require SSL termination, which means sharing your certificate or having the vendor issue one. Radware's SecurePath architecture is specifically designed to avoid this requirement through out-of-path deployment. If certificate sharing is a hard blocker in your organization, Radware or an on-premises deployment of F5 BIG-IP Advanced WAF are the options to evaluate.
Which tools in this roundup support Kubernetes environments?
Radware Cloud WAF Service explicitly supports Kubernetes deployments. F5 BIG-IP Advanced WAF supports containerized environments through its declarative API model and cloud deployments. If Kubernetes-native WAF policy management is a requirement, verify the specific integration mechanism with each vendor, as support depth varies.
How do these tools map to NIST CSF categories?
All seven tools cover PR.PS (Platform Security), PR.IR (Technology Infrastructure Resilience), and DE.CM (Continuous Monitoring). F5 BIG-IP Advanced WAF, FortiWeb, and Radware additionally cover DE.AE (Adverse Event Analysis), reflecting deeper behavioral analytics and event correlation capabilities. If your compliance program requires specific NIST CSF coverage documentation, request the vendor's mapping artifacts directly.
