Managed DDoS Protection for Insurance: Why Always-On Defense Is Essential

According to the State of Application Security 2025, web applications faced a sharp rise in hostile traffic, with 4.8 billion attacks blocked and 1.52 billion DDoS incidents affecting nearly 70% of monitored applications. APIs became the primary target, seeing 388% more DDoS attacks per host than websites, signaling a shift toward precision, application-layer disruption.

For insurance platforms, the impact is direct and measurable. During the same period, overall attack volumes increased by 309%, while DDoS activity surged by 350%. These attacks are concentrated on critical digital workflows such as claims processing, policy issuance, and renewals, where even short disruptions translate into operational delays, customer friction, and revenue impact.

In an industry built on trust, availability is a business promise. Even brief downtime disrupts revenue and compliance, making managed, always-on DDoS protection a core requirement for insurance resilience.

Application-Layer DDoS Attacks on Insurance Platforms

Insurance platforms are prime targets because nearly every interaction trigger compute-heavy backend workflow, creating an asymmetry that attackers can easily exploit.

1. Computational Asymmetry: The Core Vulnerability

A single action on an insurance platform, such as requesting a quote or recalculating a premium, can trigger a resource-intensive backend workflow. Each request activates underwriting rules, actuarial calculations, eligibility checks, and pricing logic that process multiple risk factors in real time. These operations are CPU-heavy and are not built to withstand continuous, automated repetition without impacting performance.

At the same time, the request drives multiple data lookups across policy records, claims history, customer profiles, and coverage rules, placing sustained load on databases and connection pools. Many workflows also depend on third-party services for enrichment data, which adds latency and further increases processing cost.

Attackers exploit this imbalance using Layer 7 DDoS attacks, sending legitimate-looking requests to high-cost endpoints. Instead of flooding the network, they exhaust compute and data resources, turning DDoS into an Economic Denial of Sustainability issue that leads to slowdowns, outages, and direct business impact.

2. The Quote Spamming Tactic

One of the most damaging application-layer patterns targeting insurers is quote spamming, where botnets repeatedly invoke “Get Quote” or “Recalculate Premium” workflows.

The impact is immediate at the backend, as systems are forced to execute actuarial computations thousands of times per minute. CPU utilization spikes, databases struggle, and connection pools are exhausted. Response times degrade into timeouts, effectively locking out legitimate customers, agents, and aggregator partners.

Because these requests are well-formed and conform to application logic, they bypass legacy DDoS defenses designed to detect abnormal traffic volumes or malformed packets. The attack succeeds quietly, degrading application performance from the inside rather than overwhelming the perimeter.

3. The API Aggregator Dilemma: Distinguishing Growth from Abuse

Modern insurance distribution is API-driven, connecting aggregators, brokers, payment providers, and third-party services in real time. When these APIs degrade, the impact cascades across the entire sales and servicing ecosystem.

The core challenge is distinguishing business growth from abuse. During renewal cycles, catastrophe events, or large partner campaigns, API traffic naturally surges. Static rate limits cannot accurately differentiate these legitimate spikes from sophisticated API-layer DDoS attacks. Set too aggressively, they block revenue-driving partners; set too loosely, they leave backend systems exposed.

This is why context-aware, behavior-based DDoS protection is essential. It evaluates request intent, execution patterns, and behavioral consistency rather than relying solely on traffic volume.

DDoS as a Smokescreen for Data and Compliance Breaches

In insurance, underlying data like PII, payment histories, and claims records, is as valuable as continuous uptime. In 2026, DDoS attacks are rarely isolated events. They are increasingly used as strategic distractions to conceal parallel, higher-impact cyber activity.

While security teams focus on mitigating a visible flood against a claims or policy portal, attackers exploit the noise to target less-monitored paths across the environment.

The Silent Attack Vectors

The traffic surge generated by a DDoS attack overwhelms logs and diverts analyst attention, enabling:

• Credential Stuffing and Account Takeover (ATO): Bots test large volumes of stolen credentials against agent portals, customer login pages, and partner APIs, often succeeding while detection systems are saturated.
• API Authorization Abuse: Attackers probe for token replay, session hijacking, or excessive permissions to extract sensitive customer data or submit fraudulent policy changes.
• Ransomware and Malware Footprints: The disruption window is used to establish persistence. Initial infections often go unnoticed until long after services are restored.

How Managed DDoS Protection Secures Insurance Platforms

In the insurance sector, relying on automated tools or expecting internal teams to “watch traffic” during an attack is no longer sufficient.

Insurance IT and security teams already juggle regulatory obligations, platform stability, partner integrations, and modernization. Investigating application-layer anomalies, API abuse, and low-rate DDoS attacks in real time, especially during crises or off-hours, is not sustainable. Managed DDoS protection fills this gap through continuous monitoring, expert intervention, and active attack handling. Here is how:

1. Adaptive, Behavior-Based Rate Control

Managed DDoS protection continuously learns normal traffic patterns across insurance portals and APIs, including quote requests, renewals, and claims submissions. Rate controls are adjusted dynamically based on behavior and go beyond static thresholds. This allows the system to recognize legitimate surges, such as renewal deadlines or catastrophe-driven demand, while throttling abnormal bursts, bot-driven floods, and request patterns designed to exhaust backend resources.

2. Protects High-Cost Workflows Like Quotes and Underwriting

Quote generation, premium recalculation, and underwriting APIs are common Layer-7 DDoS targets because they trigger complex actuarial logic and multiple backend dependencies. Managed DDoS protection continuously monitors these high-risk endpoints, blocking abnormal request patterns while ensuring genuine policyholders, agents, and aggregators retain uninterrupted access.

3. Blocks Bot-Driven Abuse That Disrupts Policy Servicing

DDoS attacks against insurers often overlap with automated abuse such as credential stuffing, account takeover attempts, and scripted API access. Managed DDoS protection includes integrated bot detection to identify hostile automation early, preventing it from degrading application performance or enabling downstream data exposure.

4. Secures API-Led Insurance Ecosystems

Modern insurance platforms rely heavily on APIs for aggregators, brokers, mobile apps, KYC providers, and payment services. API-layer DDoS attacks can disrupt distribution and servicing even when customer portals appear online. Managed DDoS mitigation validates request behavior through schema enforcement, enforces adaptive rate controls, and limits abusive API bursts to maintain reliability across the entire insurance ecosystem.

5. Maintains Stability During Event-Driven Traffic Surges

Insurance traffic is highly event-driven. Natural disasters, regulatory deadlines, or mass renewals can cause sudden spikes in portal and API usage. Attackers exploit these moments to blend DDoS traffic with legitimate demand. Managed protection uses behavioral baselines to distinguish genuine surge traffic from attack activity, keeping response times stable and workflows operational.

6. Enables Continuous Monitoring and Expert Intervention

Managed SOC teams monitor live traffic around the clock, detecting subtle attack patterns, and adjusting defenses in real time. When attackers attempt to mimic human behavior or bypass automated controls, experts investigate anomalies, refine policies, and stop attacks early, without disrupting legitimate insurance operations.

7. Protects Origin Infrastructure and Prevents Backend Exposure

Attackers often attempt to bypass perimeter defenses by targeting origin servers or hidden APIs directly. Managed DDoS protection routes traffic through secure edge layers, scrubs malicious requests upstream, and prevents direct-to-backend access, ensuring core insurance infrastructure remains stable under attack.

AppTrana implements managed DDoS protection specifically designed to handle the scale, complexity, and risk profile of modern insurance applications.
Unlike many providers that treat advanced DDoS capabilities as optional add-ons, AppTrana bundles behavioral-based DDoS protection and unmetered mitigation by default.

1. Unmetered DDoS Protection with Always-On Edge Mitigation:

AppTrana provides unmetered DDoS protection, absorbing volumetric and application-layer attacks without limits on bandwidth, requests per second, or attack duration. This is critical for insurance environments, where attacks against quote engines or claims portals often persist for days.

All traffic is processed through AppTrana’s edge infrastructure, ensuring large floods are mitigated without introducing cost variability or backend saturation.

2. AI-Driven Behavioral Traffic Analysis (No Add-Ons Required)

Instead of static thresholds, AppTrana’s behavioral based AI engine continuously profiles normal traffic patterns across insurance workflows such as quote generation, renewals, and claims submission.

The engine evaluates parameters including request frequency, navigation paths, session behavior, execution sequences, and client characteristics. When traffic deviates from learned baselines, mitigation controls are automatically tightened, allowing legitimate demand while suppressing abuse that mimics real users.

3. Application-Layer DDoS Protection for Compute-Heavy Endpoints

Insurance DDoS attacks frequently exploit endpoints that trigger actuarial logic, underwriting rules, database correlation, and third-party enrichment APIs. AppTrana focuses on application-layer DDoS mitigation, identifying abnormal execution patterns.

Requests that repeatedly invoke high-cost backend logic are flagged by behavioral models at the WAAP layer. The Indusface managed services team works in conjunction with in-house SOC teams at the Insurance provider and takes mitigation measures before they can exhaust application servers, databases, or connection pools.

4. API-Aware DDoS Controls for Aggregators and Brokers

AppTrana protects insurance APIs using schema validation, behavior-based rate controls, and API context awareness. This ensures that trusted aggregators, brokers, and mobile applications continue operating normally while automated API floods, replay patterns, and abusive bursts are throttled or blocked.

By applying API-specific behavioral enforcement, AppTrana prevents silent backend degradation even when perimeter traffic appears legitimate.

6. Origin Protection and URI-Level Access Control

AppTrana enforces origin protection by ensuring all inbound traffic is routed through its secured edge. URI blacklisting is used to block external access to non-public endpoints, while internal URLs are restricted to approved IP ranges.
