It intercepts every script before it reaches the user, captures the full payload, and analyses runtime behaviour in real time. Third-party scripts power modern websites. Analytics, chat, payments, advertising, and session replay tools all inject JavaScript that runs directly in your visitors' browsers. You didn't write that code. You don't control when it changes. And you have no idea what it does at runtime. That is the client-side blind spot. The three problems cside solves 1) Every third-party script is a blind spot. Analytics, chat, payments, ads: you didn't write it, you don't control it, and you have no idea what it does at runtime inside a real browser. 2) PCI DSS 4.0.1 requirements 6.4.3 and 11.6.1 are now enforced. Most companies have no idea how to meet them, and their existing vendors don't cover it. WAFs, CDNs, and tag managers were never built for this problem. 3) AI agents and bots are now targeting high-value web workflows including checkout, login, and form submission in ways that WAFs and CDN-layer tools were never designed to catch. The attack surface has moved into the browser. The tools haven't. What you get with cside 1) Visibility you have never had. Every script on every page, classified, behavioural-profiled, and monitored continuously. Not what a scanner saw on its last crawl. What actually ran in a real user's browser, in real time. 2) Compliance, done. 6.4.3 and 11.6.1 documentation generated automatically. Auditor-ready output without manual effort. QSA-validated. No CSV exports to fill in by hand. 3) Real-time blocking. Malicious or anomalous script behaviour stopped at the browser layer before data leaves the page. Not flagged for review after the fact. Stopped before exfiltration occurs. Why CSPs and crawlers cannot solve this A Content Security Policy tells the browser which domains are allowed to load scripts. It has no visibility into what those scripts execute. A script served from a trusted domain, after being compromised through a supply chain attack, passes every CSP check and still skims card data from your checkout page. Crawlers and scanners have a different problem. Bad actors detect them and serve clean content to the scanner, then flip to malicious for real users. What the scanner saw and what your customers experienced are two different things. WAFs and CDNs operate at the network layer. They cannot see inside the browser. They check what loads, not what executes. cside sits in the delivery path of every script. It captures what scripts actually do in real user sessions. Deployment: One script tag. Under ten minutes. No managed crawl setup, no session tokens, no captcha bypasses required. Pricing: Free tier available to see your script exposure before buying. Business and Enterprise tiers for teams managing compliance, multi-domain environments, and advanced governance. Transparent pricing. No contract required to prove compliance to your QSA before you commit. Frequently asked questions 1) What makes cside different from a Content Security Policy?: A CSP controls which domains scripts can load from. It cannot analyse what those scripts execute at runtime. cside captures the full payload of every script and analyses its behaviour inside real user browsers, giving you the runtime visibility that CSP was never designed to provide. 2) What PCI DSS requirements does cside address?: cside is built specifically around requirements 6.4.3 and 11.6.1 of PCI DSS 4.0.1. It generates the authorised script inventory required by 6.4.3 and provides the ongoing change detection and monitoring required by 11.6.1, with QSA-validated audit-ready output. 3) How is cside different from a WAF or CDN security feature?: WAFs and CDNs operate at the network or server layer and have no visibility into what JavaScript executes inside a user's browser. cside operates at the browser layer. It is a dedicated product for client-side security, not a feature bolted onto an existing network tool. 4) Does cside detect AI agents and bots?: Yes. cside detects AI agents and bots targeting high-value web workflows including checkout, login, and form submission, covering a threat class that network-layer tools were not designed to address.

[Application Security Software](https://www.g2.com/categories/application-security) ## What Software Categories Are Similar to Application Shielding Software? - [Runtime Application Self-Protection (RASP) Tools ](https://www.g2.com/categories/runtime-application-self-protection-rasp-tools) --- ## What Are the Most Common Questions About Application Shielding Software? *AI-generated · Last updated: June 3, 2026* ### Application Shielding platforms with proven track records in mobile banking and fintech apps protecting against real fraud attacks Based on G2 reviews, these products are most often mentioned for mobile app protection and fraud defense. - [Appdome](https://www.g2.com/products/appdome) — mobile banking fraud and bot protection. - [DexProtector](https://www.g2.com/products/dexprotector) — Android obfuscation with low app impact. - [Zimperium Mobile Application Protection Suite (MAPS)](https://www.g2.com/products/zimperium-mobile-application-protection-suite-maps) — runtime threat detection for mobile apps. ### Which Application Shielding tools prevent binary reverse engineering while keeping app launch times fast and user experience clean Based on G2 reviews, these products are commonly used to harden apps without heavy user-facing disruption. - [Appdome](https://www.g2.com/products/appdome) — no-code protections with streamlined releases. - [DexProtector](https://www.g2.com/products/dexprotector) — obfuscation with minimal launch impact. - [PreEmptive](https://www.g2.com/products/preemptive) — obfuscation for deploy-time code protection. - [Jscrambler](https://www.g2.com/products/jscrambler) — JavaScript obfuscation with support guidance. ### Application Shielding tools scaling seamlessly across mobile apps handling millions of daily transactions without bottlenecks According to verified users, scalable application shielding is usually tied to low-friction deployment, centralized control, and protections that fit normal release workflows. Reviews in this category repeatedly highlight build-process integration, the ability to apply protections without major code changes, and support for frequent updates across mobile environments. Buyers also point to fast rollout of new controls as threats evolve, especially when security teams need to protect sensitive transactions without creating bottlenecks for development. At the same time, some reviewers note that configuration depth, build limits, or longer compile times can affect implementation pace, so scalability is often about both protection breadth and operational efficiency. ### What are the most important features in application shielding software According to verified users, the most important features in application shielding software center on protecting apps during build time and runtime while keeping delivery practical. Recurring themes in recent reviews include anti-tampering, obfuscation, root or jailbreak detection, anti-debugging, code and binary protection, certificate or SSL pinning, encryption, fraud prevention, bot defense, threat event visibility, and telemetry for investigation. Buyers also value no-code or low-code implementation, support for CI or build workflows, over-the-air policy updates, and dashboards that simplify policy management. Ease of setup matters too, but reviewers often note that advanced configurations still require planning and testing to balance security strength with app performance and user experience. ### How do teams use Application Shielding for release workflows G2 reviewers mention that teams use Application Shielding to add protections as part of normal build and release workflows instead of relying on large engineering rework. In recent reviews, users describe applying hardening, anti-tampering, obfuscation, runtime checks, and fraud controls during build time so apps can move through QA and production with fewer manual steps. This helps security teams test and tune controls without deeply changing source code, while developers keep shipping on regular schedules. Reviewers also connect shielding tools to shorter time to market, easier iteration across releases, and better coordination between security and development. Common friction points include onboarding complexity, documentation gaps, and build-time increases for some implementations.
