# Best Client-Side Protection Solutions *By [Lauren Worth](https://research.g2.com/insights/author/lauren-worth)* Client-side protection solutions help businesses protect their customers against end-user data exfiltration and shield websites from threats related to vulnerable source code. These solutions analyze script behavior in real time, provide actionable insights in a single dashboard view, and deliver alerts to mitigate harmful script activity. These front-end security tools allow organizations to gain visibility and control over first and third-party website code, reducing the risk of supply chain fraud and preventing data breaches and client-side attacks. They identify and prevent web skimming attacks and protect websites against malicious script injections and unauthorized third-party data collection. Client-side protection software offers protection against client-side attacks, including keylogging, form jacking, cross-site scripting (XSS), data harvesting (PII harvesting), digital skimming, and Magecart. These tools ultimately help businesses stay compliant with PCI DSS and other financial and data privacy regulations. Client-side protection tools have some overlap with [attack surface management software](https://www.g2.com/categories/attack-surface-management) and [risk-based vulnerability management software](https://www.g2.com/categories/risk-based-vulnerability-management) as all three are deployed to identify vulnerabilities and reduce the attack surface. However, unlike the other two, client-side protection software focuses specifically on securing the client-side environment, typically within web browsers or mobile devices. To qualify for inclusion in the Client-side Protection Solutions category, a product must: - Offer continuous scanning of websites and applications for suspicious activities, prompt alerts, and capabilities to respond to client-side threats - Offer visibility into an application’s third-party components - Prevent credential stuffing on the client side to block account takeover attempts - Protect against a wide range of client-side threats, including XSS attacks, formjacking, digital skimming, and Magecart exploits - Provide actionable insights and reporting features for clear visibility into security incidents, vulnerabilities, and compliance status ## How Many Client-Side Protection Solutions Products Does G2 Track? **Total Products under this Category:** 18 ### Category Stats (Jul 2026) - **Average Rating**: 4.44/5 The average rating of products in this category, based on all submitted ratings - **Top Trending Product**: Cloudflare Application Security and Performance (+0.04%) - Among all products in this category, Cloudflare Application Security and Performance recorded the largest rating increase compared to last month *Last updated: July 07, 2026* ## How Does G2 Rank Client-Side Protection Solutions Products? **Why You Can Trust G2's Software Rankings:** - 30 Analysts and Data Experts - 700+ Authentic Reviews - 18+ Products - Unbiased Rankings G2's software rankings are built on verified user reviews, rigorous moderation, and a consistent research methodology maintained by a team of analysts and data experts.

[cside](https://www.g2.com/products/cside/reviews) What is cside? cside is a browser-layer security platform that gives organisations complete visibility and control over the third-party JavaScript running on their websites. 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. **Average Rating:** 4.8/5.0 **Total Reviews:** 12 **Who Is the Company Behind cside?** - **Seller:** [cside](https://www.g2.com/sellers/cside) - **Company Website:** https://cside.dev/?utm_source=thefundingletter.beehiiv.com&utm_medium=newsletter&utm_campaign=the-funding-letter-1420-may-20 - **Year Founded:** 2024 - **HQ Location:** San Francisco, US - **LinkedIn® Page:** https://www.linkedin.com/company/csidedev (21 employees on LinkedIn®) **Who Uses This Product?** - **Company Size:** 83% Small-Business, 17% Mid-Market #### What Are cside's Pros and Cons? **Pros:** - Monitoring (3 reviews) - Helpful (2 reviews) - Threat Detection (2 reviews) - Accuracy of Information (1 reviews) - Alert Notifications (1 reviews) **Cons:** - Difficult Initiation (1 reviews) - Navigation Issues (1 reviews) - Not Intuitive (1 reviews) - Not User-Friendly (1 reviews) - UX Improvement (1 reviews) ### What Do G2 Reviewers Say About cside? *AI-generated summary from verified user reviews* **Pros:** - Users appreciate the **intuitive monitoring** of cside, enabling easy tracking of scripts and compliance effortlessly. - Users value the **control over third-party scripts** that c/side provides, enhancing security and transparency on their sites. - Users praise the **exceptional threat detection** of c/side, significantly enhancing their security and protecting against overlooked cyber threats. - Users commend the **accuracy of information** provided by c/side, significantly enhancing their security posture and compliance efforts. - Users value the **alert notifications** for effectively identifying issues early, enhancing security and compliance in their browsers. **Cons:** - Users find the **difficult initiation** process challenging, but once understood, the system's power becomes evident. - Users face **navigation issues** , finding the interface non-intuitive and requiring time to learn its various functions. - Users find the interface **not intuitive** , requiring time to understand script grouping and display logic effectively. - Users find the **interface unintuitive** , requiring trial and error to navigate effectively and understand script behavior. - Users notice **rough edges and occasional issues** with the product, though support helps mitigate these concerns efficiently. #### What Are Recent G2 Reviews of cside? **"[Great price to protect and secure marketing data](https://www.g2.com/survey_responses/cside-review-12873342)"** **Rating:** 5.0/5.0 stars *— Verified User in Marketing and Advertising* [Read full review](https://www.g2.com/survey_responses/cside-review-12873342) --- **"[A simple PCI DSS solution backed by outstanding support](https://www.g2.com/survey_responses/cside-review-12189954)"** **Rating:** 4.5/5.0 stars *— Frédéric B.* [Read full review](https://www.g2.com/survey_responses/cside-review-12189954) --- ### 5.

[ScriptPatrol](https://www.g2.com/products/scriptpatrol/reviews) ScriptPatrol is client-side (browser-layer) security monitoring for any website that handles payments or logins — e-commerce, SaaS, banking, booking, and healthcare. Your firewall and server can't see the JavaScript that runs in your customers' browsers, and that's exactly where Magecart, formjacking, and e-skimming attacks operate. ScriptPatrol can see it. It loads your real checkout, login, and admin pages the way a visitor's browser does — with no tag to embed, no agent to install, and zero impact on site performance — fingerprints every script (external and inline) with a SHA-256 hash, and compares each scan against a verified baseline. When an unexpected or unauthorized script appears or changes, it is risk-scored and you are alerted by email and Slack with a plain-language explanation of what changed. Every monitored page gets a transparent A+ to F Security Score built from your security headers, your TLS configuration, and live script integrity. ScriptPatrol also identifies the vendor behind each third-party script, flags look-alike (impersonating) domains, maps where each page sends data, and checks scripts against known-vulnerable library versions and known-malware/phishing hosts. Routine vendor updates are recognized and filtered out, so an alert always means something worth a look. It scans reliably even on sites behind Cloudflare and bot protection, and detects challenge pages so they are never mistaken for real results. Export PDF reports with a full script inventory and change history — the same evidence PCI DSS 6.4.3 and 11.6.1 ask for, where they apply. **Who Is the Company Behind ScriptPatrol?** - **Seller:** [ScriptPatrol](https://www.g2.com/sellers/scriptpatrol) - **Year Founded:** 2025 - **HQ Location:** N/A - **LinkedIn® Page:** https://www.linkedin.com/company/scriptpatrol (1 employees on LinkedIn®) ### 18.
