Every request is protected with a one-time token generated client-side and verified via API. The response includes a verdict (Allow, Challenge, or Block) with risk scores, triggered signals, and enrichment data. Threat coverage: account takeover, credential stuffing, brute force attacks, fake registrations, data scraping, form spam, API abuse, coupon fraud, and multi-accounting. Core protection works out of the box. Risk scoring, custom rules, and rate limiting let you adapt to any threat specific to your business. BotBye detects phishing sites impersonating your brand, including HTML clones, reverse proxies, and custom-built fakes, and responds with takedowns, counter-attacks, and compromised user flagging.

About

cside is a browser-layer security platform that gives you visibility for every visitor, human or agentic. Security, fraud prevention, privacy and compliance, all from a single script. Unlike traditional WAFs and server-side security tools, cside operates directly in the browser environment, monitoring every third-party script loaded on your pages in real time. This means threats that bypass your backend defences are caught at the point of execution. What cside does: Script Monitoring and Control: cside inventories, monitors, and enforces policy on every third-party JavaScript tag running on your site. 100% session coverage, no sampling. Every script. Every page load. Detect supply chain attacks, shadow scripts, and unauthorised tag injections before they reach your customers. PCI DSS 4.0.1 Compliance: cside is the fastest path to meeting PCI DSS 4.0.1 requirements 6.4.3 and 11.6.1. Automated script authorisation, tamper detection, and continuous monitoring satisfy QSA requirements without manual effort. Validated by VikingCloud. Device Intelligence: Persistent, privacy-safe device intelligence using 102+ signals and 40+ hashed attributes. 99.7% fingerprint accuracy enables fraud prevention, bot detection, and session continuity across logins, checkouts, and account actions. AI Agent and Bot Detection: Identify and classify AI crawlers, headless browsers, and automated agents interacting with your site. Protect pricing data, inventory, and content from scraping and abuse. Chargeback Evidence: Capture cryptographically verifiable session evidence at checkout to dispute fraudulent chargebacks. Reduce dispute losses without adding friction to genuine customers. Who uses cside: E-commerce retailers, payment service providers, digital agencies, travel and hospitality platforms, iGaming and betting operators, financial services firms, and SaaS companies managing PCI compliance, fraud risk, and client-side attack surface across high-traffic web environments. Deployment: One-line script tag. No proxy. No latency impact. Up and running in under 5 minutes. SOC 2 Type II certified. PCI SAQ-D validated.

Pros from Real Users

Pros

  • The team behind cside are passionate about the product. Support is great and they are always adding to and developing what they have. The platform itself has provides a huge amount of insights and the software was very easily integrated.
  • Highly engaged team, constantly looking to improve their product, very susceptible to feedback, very fast. Honestly, great experience
  • - We signed up with them for script monitoring, which it did. - We were probably one of their first customers - Their team was very hungry and fast at helping. Very clearly wanted to build the best product. - Our PCI assessment went smoothly - Script observability appeared way more through than other tools I tried - We recently started using their product for account take-over risk. And it has caught a lot of weird behaviors of users.
  • Full visibility into what's running, seeing every script, and where it comes from, what it's doing, and whether it's compliant or risky. The hybrid proxy intercepts scripts before they reach the browser. I achieve 100% session visibility with zero added latency, deployed via a single script tag. It also covers compliance well, helping me meet PCI DSS 4.0.1, DORA, and GDPR requirements without worrying about performance.
  • - easy to use - literally no alternatives for most of their products - amazing support and product updates
  • I use cside to see what third-party scripts are running on my website. cside's free tier was easy to deploy, just drop in three lines of code and you’re live. Within seconds of deployment, the dashboard started surfacing telemetry on third-party JavaScript: origin domains, initiating scripts, sync vs async loading, even full script contents.
  • 1. Eliminates Third-Party Blind Spots Traditional Web Application Firewalls (WAFs) only see traffic at the server level. c/side provides real-time visibility into what scripts are actually doing on the client side, effectively neutralizing "Magecart-style" attacks where hackers inject malicious code into trusted third-party plugins. 2. High Performance with Zero Latency One of the biggest hurdles for security tools is website speed. c/side uses a sophisticated proxy architecture that inspects scripts without slowing down the page load, ensuring that security doesn't come at the cost of user experience or SEO. 3. Simplified Compliance (PCI DSS 4.0) New financial regulations (like PCI DSS 4.0.1) now strictly require companies to manage and authorize all scripts on payment pages. c/side automates this entire process, making it an "easy button" for compliance teams and preventing heavy fines.
  • the easy way of installation and keep it running. users are not impacted during installation or afterwards while they are getting a better protected environment.
  • Setup is fast, used them initially for straightforward compliance and bot detection turns out to be better than other providers.
  • Really good for AI agent detection & client side security, very easy to use, features I haven't seen at competitors- also great support :)

AI Security Supported

The detection engine uses an open-source LLM that runs entirely inside a self-hosted environment

The cside AI engine detected that the modified script exhibited keylogger behavior and was flagged as malicious. Customers can then review the script and, if necessary, block the corresponding hash values.

cside is a cutting-edge client-side security solution designed to protect organizations from the growing threat of browser-based attacks. Unlike traditional security tools that rely solely on threat feed intelligence, cside employs a fully autonomous detection system that uses historical context and AI to analyze the behavior of third-party scripts. This proactive approach allows cside to identify and block potential threats before they can reach your users, ensuring robust protection against zero-day vulnerabilities and supply chain attacks. With its unique multi-layer solution, cside offers unparalleled defense for client-side applications, making it an essential tool for any organization looking to safeguard their web presence.

Browser Security Supported

100 % session coverage, DOM-level diffing, conditional threat detection (geo/time/user cohort). c/side sits in the path of every third-party request, fetches the actual JavaScript, and inspects it in real time. So malicious code is blocked before the browser can execute a single line.

Compliance Supported

VikingCloud’s independent assessment confirms that, when properly configured, cside fulfills these requirements by continuously analyzing integrity and, if necessary, blocking scripts in real-time. The cside platform offers a dedicated PCI DSS dashboard that explicitly covers insights into 6.4.3 and 11.6.1 requirements.

GDPR Compliance Supported

cside only stores the requester’s IP address for incident scoping; that data is never brokered or used for advertising. All collected data remains in cside managed clusters hosted in AWS.

IT Security Supported

Stop Magecart, formjacking, token hijacking, cryptojacking, and more! By integrating client-side protection every third, fourth, and nth party script behavior is monitored for malicious signals. cside delivers full–spectrum visibility and control over all third party scripts executed in the user’s browser 100 % of the time without sampling.

Network Management Supported
PCI Compliance Supported

By providing real-time payload inspection, automated blocking, full historical payload storage, and auditor-ready reports that map directly to the testing procedures in PCI DSS 4.0.1.

Website Security Supported

VikingCloud noted that the cside platform intercepted and blocked the third-party script actively to prevent data leakage.
