API DDoS Protection – Key Features
Behavioral Detection as Default
AppTrana learns normal traffic patterns for each API across URI, method, token, and session. This behavioural baseline lets us instantly flag anomalies, including low-rate distributed swarms where thousands of IPs send just 1–2 requests per second. No enterprise add-ons required.
Experience Reliable API Protection with Indusface
Indusface protects 8 API hosts and the behavioral DDOS is very helpful in dynamic rate-limiting. We haven't seen any downtime.
Company Size: 50M - 250M USD
Industry: Travel and Hospitality
Unmetered Attack Traffic
Most providers meter DDoS protection by requests-per-second. The bigger the flood, the bigger your bill. AppTrana takes a different approach: all attack traffic is absorbed at no cost, no matter how large or how long it lasts. You only pay for clean, legitimate traffic that reaches your origin.
Only legit traffic to your Website with API Protection
The constant monitoring of web applications against cyber threats allows us to work stress-free, even in a complex environment. The software is highly effective in securing the network and revealing application-layer susceptibilities in real time.
Industry: Retail
Always-On, Auto-Scaling Edge Shield
AppTrana scrubs malicious traffic at the edge before it touches your APIs or gateways. Capacity scales automatically during spikes, without manual playbooks. Locked-down origin IPs, allowlist-only ingress, and mutual TLS ensure attackers can’t bypass protection and reach your backend directly.
Three Years of Continuous Application Uptime Reported With AppTrana WAF
We have not seen any downtime from the last 3 years or any bug in the application
Industry: Consumer Goods
Adaptive, Low-Latency Mitigation
AppTrana applies smart blocks, dynamic throttling, challenges, and tarpitting to stop malicious traffic while keeping legitimate API requests flowing. Our globally distributed edge ensures these protections add minimal latency, so your production APIs and microservices stay fast and resilient.
Adaptive Security and API Protection Enhance Web Application Security Measures
We are extremely satisfied with the services. We are specifically impressed by Exceptional Protection, which has Adaptive Security Protection, which creates rules on the fly by looking at the traffic and web requests, which has fewer false positives, so we can channelize our efforts effectively.
Company Size: 500M -1B USD
Industry: Insurance
24x7 managed SOC
Our managed SOC continuously monitors your APIs, fine-tunes rules mid-attack, and provides root cause analysis(RCA). Every incident is documented with clear timelines of traffic patterns, mitigations, and outcomes, giving you compliance-ready reports for internal audits, regulators, and the board.

Other Platforms vs AppTrana API
API DDoS pricing model
Typical API Security Platforms
- Charge per request or per Gbps cleaned, so DDoS and bot bursts can drive up bills.
- Behavioural or application layer DDoS is often a separate add on SKU with its own pricing.
- You pay for all traffic that hits the edge, even if most of it is attack traffic.
AppTrana API Security
- You pay only for clean traffic that reaches your origin servers, not for malicious DDoS volume.
- Behavioural and application layer DDoS for APIs is included, not sold as a separate add on.
- Unmetered protection keeps DDoS costs predictable even during large or sustained attacks.
Behavioural DDoS detection and coverage
Typical API Security Platforms
- Rely on simple rate limits and static thresholds on API endpoints.
- Behavioural and ML driven DDoS is available only as a higher tier or specialist add on.
- 24x7 DDoS SOC / managed mitigation is usually a premium enterprise add-on, so day-to-day tuning and whitelisting fall on your team.
AppTrana API Security
- Uses behavioural and AI driven models that look at method, path, IP, geography and patterns specific to API traffic.
- Protection extends across Layer 7 volumetric attacks and slow or low and slow patterns that bypass basic rate limits.
- DDoS controls are fully managed by a 24x7 SOC that baselines, tunes and maintains safe policies for your APIs at no extra cost.
Scale and unmetered protection for APIs
Typical API Security Platforms
- DDoS capacity is tied to plan limits; large API spikes can hit caps or trigger emergency upgrades.
- CDN and DDoS are often separate modules, which can add complexity and gaps when traffic shifts.
- High concurrency API workloads risk latency spikes under attack traffic.
AppTrana API Security
- Unlimited protection against large volumetric Layer 7 attacks, built on scalable infrastructure designed to absorb surges.
- Integrated CDN and DDoS stack keep API latency low even during high traffic or attack windows.
- Unmetered DDoS and bot mitigation mean no surprise overages when APIs grow or come under stress.
Uptime and business continuity during DDoS
Typical API Security Platforms
- Focus on stopping the attack but do not guarantee 100 percent uptime for the protected APIs.
- If the DDoS layer/platform fails, APIs may go down with no automatic bypass.
- SLAs often lack a meaningful penalty clause or SOC-backed response commitment.
AppTrana API Security
- 100 percent uptime guarantee for the protection layer, backed by a penalty clause in the SLA.
- Auto-bypass ensures traffic is routed safely so your APIs stay reachable even if the platform faces an issue.
- A 24x7 SOC monitors DDoS events and coordinates response, so your teams are not alone during major incidents.

Frequently asked questions, answered.
Most providers charge extra for behavioural DDoS or restrict protection based on requests-per-second (RPS). AppTrana includes behavioural detection in every plan and absorbs all attack traffic at no extra cost. You only pay for clean traffic.
It means there are no hidden caps or RPS-based tiers. Whether it’s 10k requests per second or a multi Tbps flood, AppTrana absorbs the attack and only forwards legitimate requests to your origin.
AppTrana learns normal traffic per API, URI, method, token, and session. This allows it to instantly flag anomalies, including low-rate distributed swarms where thousands of IPs send just 1–2 requests per second.
No. AppTrana mitigates attacks at the global edge with an optimized inspection path. Latency overhead is negligible (measured in milliseconds) and tuned to keep production APIs and microservices fast.
Yes. AppTrana works seamlessly with API gateways, ingress controllers, and service meshes. Onboarding is as simple as a DNS change or IP cutover.
Your traffic is automatically scrubbed by AppTrana’s behavioural engine. Simultaneously, our 24x7 SOC monitors patterns in real time, fine-tunes rules, and provides updates until the attack subsides.
AppTrana provides full observability: live dashboards, detailed logs, alerts, and post-incident forensic reports. You also get compliance-ready documentation for audits and regulators.
AppTrana prevents bypass with origin shielding, strict allowlists, and mutual TLS. This ensures that all traffic must pass through the DDoS scrubbing layer before reaching your backend.
