| Criteria | cside | Cloudflare Client-Side Security (Page Shield) | Why It Matters | What the Consequences Are |
|---|---|---|---|---|
| Approach used | Live in-session monitoring + server-side AI payload analysis | Sampled CSP reporting + static AI code analysis (Advanced tier) | ||
| Monitors 100% of sessions (no sampling) | ✓ | ✗ | Attacks can fire between samples or only for a subset of visitors | Cloudflare samples only a small fraction of traffic (~1%); rare or targeted skimmers go unseen |
| Runtime & DOM-level behavioral detection | ✓ | ✗ | Observes how scripts actually behave as they execute, including DOM changes | Static analysis of the fetched file misses DOM-based and execution-time attacks |
| Detects dynamic / targeted payloads (per user, time, location) | ✓ | ✗ | Identifies attacks that only trigger for some users, times, or geographies | A skimmer serving to 1 in 1,000 visitors never appears in a fetched, sampled copy |
| Analyzes the exact script the user received | ✓ | ✗ | Aligns analysis with what really executed, not a copy fetched separately | Cloudflare downloads from its own IPs with different headers, often not the user's payload, and often it can't fetch the script at all |
| AI / ML script analysis | ✓ | ✓ (Advanced tier) | Detects novel threats through code and behavior modeling, not just threat feeds | Cloudflare's classifier is Advanced-tier only and skips scripts over 300 KB |
| Full payload analysis regardless of script size | ✓ | ½ | Large bundled scripts are common, and they are where payloads hide | Cloudflare's classifier only runs on scripts up to 300 KB |
| Complete historical tracking & forensics | ✓ | ½ | Needed for incident response, auditing, and compliance | Cloudflare deletes resource data after 30 days without a new report |
| Archives the actual payload as evidence | ✓ | ✗ | Auditors and responders need the real attack code, not just a score or a log | Without the archived payload you can't prove what an attack actually did |
| Works on any stack (no CDN / WAF lock-in) | ✓ | ✗ | Client-side risk exists no matter which CDN or firewall you run | Cloudflare Client-Side Security requires routing your domain through Cloudflare |
| QSA-validated PCI DSS dashboard | ✓ (VikingCloud) | ½ | Independent QSA validation is the most reliable proof a solution meets PCI DSS | Cloudflare has a QSA applicability guide but a generic monitoring UI, not a PCI-mapped dashboard |
| In-product PCI script justification workflow (6.4.3) | ✓ | ✗ | 6.4.3 requires written business and technical justification for every script | Cloudflare exports a CSV; teams document and justify each script manually |
| Usable script inventory & management UI | ✓ | ✗ | Reviewing, approving, and justifying every script needs a real workspace, not a data export | Page Shield surfaces a list; teams end up tracking scripts and approvals by hand in spreadsheets |
| Covers PCI DSS 6.4.3 and 11.6.1 | ✓ | ✓ (Advanced tier) | Both address the requirements; the depth of evidence and workflow differs | Cloudflare's coverage needs the paid Advanced add-on. The free tier is not enough |
| Free CSP reporting endpoint | ✓ (every plan, including free) | ½ | CSP violation reporting is the baseline for client-side visibility | Cloudflare's content security rules are capped at 5 and gated to Advanced |
| SOC 2 Type II | ✓ | ✓ | Shows consistent operational security controls over time | A baseline both vendors meet |
| Ticketing Integrations (Linear, Jira) | ✓ (both Linear and Jira) | ✗ | Native integrations let security alerts flow into existing developer workflows | Without native ticketing, teams create tickets manually, slowing response times |

| 2026 Globee® Cybersecurity Awards: Client-Side Security | 🥇 Gold (Best of Category) | 🥈 Silver |
"Bad actors that target large brands will try to reverse engineer what security is present. Client-side security suffers especially badly from this if the detections are solely done client-side. The result is simple: it's like playing minesweeper with the bombs exposed. Client-side security can not solely rely on client-side monitoring."
- Simon Wijckmans, CEO, cside
| Criteria | cside | Reflectiz | Why it matters | What the consequence is |
|---|---|---|---|---|
| Approach | Script Method + Scan Method | Remote scanner | cside includes scanner-based coverage, but does not depend on scanning alone. | Teams get optionality instead of being locked into scanner-only blind spots. |
| Real-user browser visibility | ✓ | ✗ | cside runs in the actual DOM of real sessions. A cloud scanner sees only what the page serves to that scanner. | A crawler can receive clean code while users receive malicious code. |
| Scanner evasion resistance | ✓ | ✗ | Attackers can vary scripts by IP, device, country, user agent, login state, or time. | Remote scans can create a false sense of coverage. |
| [PCI DSS 4.0.1](https://www.pcisecuritystandards.org/document_library/) evidence + SAQ D | ✓ | ½ | PCI evidence needs to satisfy assessors and remediation reviews. | Self-described reporting may still need independent validation. |
| SOC 2 Type II | ✓ | ✗ | Enterprise buyers often require independent operational assurance. | Missing SOC 2 Type II can become a procurement blocker. |
| Public status page & uptime transparency | ✓ | ✗ | You can independently check live uptime and incident history before and after you buy, instead of first hearing about outages from your own users. | Reflectiz publishes no public status page or uptime SLA, so buyers can't independently verify availability. |
| Browser-side blocking | ✓ | ½ | Any browser-side blocking control must run inside the application. | Reflectiz accepts the same application-interaction class of risk it criticizes. |
| Public pricing | ✓ | ✗ | Public pricing makes budget planning easier. | Hidden pricing adds buying uncertainty. |
Your site's availability becomes dependent on Trusted Knight's uptime. This is a meaningful risk for financial institutions with SLA obligations.
Every request to your site makes an additional network hop through the proxy. For financial institutions where session latency affects conversion and customer experience, the round-trip adds overhead.
| Criteria | cside | Trusted Knight | Why It Matters | What the Consequences Are |
|---|---|---|---|---|
| Deployment Architecture | Lightweight script deployed on your site | DNS proxy that routes traffic through Trusted Knight infrastructure | Your architecture choice shapes operational risk, latency, and third-party uptime dependency | DNS proxies create a single point of failure and add latency to every request |
| Catches malicious code in the browser before it steals user data | ✓ | ½ | Client-side attacks execute in the browser, not on the network | Network-layer inspection misses browser-only threats like DOM manipulation and post-load injections |
| Where monitoring happens | Browser runtime environment | Network layer / session traffic inspection | Browser-level monitoring shows what users experience | Network-only monitoring cannot observe what scripts do after page delivery |
| Website performance impact | ✓ Minimal | ✗ High risk | Extra network hops add latency that affects conversion rates and user experience | DNS proxies route all traffic through third-party infrastructure, adding overhead to every request |
| Prevents [web skimming](https://en.wikipedia.org/wiki/Web_skimming) and phishing from UI manipulation | ✓ | ½ | Skimming and UI phishing happen in the DOM after the page loads | Without browser-level visibility, DOM-based attacks run undetected |
| Monitors Third Party Script Injections | ✓ | ½ | Third-party scripts are the primary vector for supply chain attacks | Missing script injection visibility leaves your site exposed to compromised dependencies |
| Device fingerprinting fraud signals | ✓ | ✗ | Device signals help identify fraud patterns and repeat offenders | Without fingerprinting, fraud teams lack session-level intelligence for risk scoring |
| Post-load script behavior monitoring | ✓ | ✗ | Many attacks activate only after page load via deferred or injected scripts | No post-load monitoring means attacks that trigger after delivery go undetected |
| Data encryption in transit | ✗ Standard TLS | ✓ | Additional encryption layers can protect data on compromised endpoints | Standard TLS is sufficient for most use cases but does not protect against endpoint malware |
| Blocks device level malware on compromised machines | ✗ Not a focus | ✓ | Endpoint malware can intercept data before it reaches the browser | No website-side security can consistently protect against malware already on a user's device. As the site owner, you cannot technically guarantee protection against pre-existing device-level threats |
cside monitors JavaScript execution and detects malicious behavior in real time. It prevents web skimming, script-based attacks, and client-side fraud while providing device fingerprinting signals for anti-fraud workflows.
Trusted Knight protects transactions from compromised user devices by inspecting session traffic and encrypting sensitive data. It reduces fraud and secures interactions even when the endpoint is infected.

| Threat Type | cside | Trusted Knight | Why It Matters | What the Consequences Are |
|---|---|---|---|---|
| [Magecart](https://en.wikipedia.org/wiki/Magecart) (Web Skimming) | ✓ | ✓ | Magecart attacks inject skimmers into payment pages to steal card data | Without detection, stolen card data leads to fraud losses and PCI violations |
| Keyloggers served through browser-layer injections | ✓ | ½ | Browser-injected keyloggers capture credentials and sensitive input in real time | Network-layer tools may miss keyloggers that activate after page delivery |
| Third-Party JavaScript Supply Chain Compromises | ✓ | ½ | Compromised [third-party scripts](https://developer.mozilla.org/en-US/docs/Web/Performance) are the most common client-side attack vector | Without script-level monitoring, supply chain attacks spread through trusted dependencies |
| DOM Manipulation / UI Phishing Detection | ✓ | ✓ | Attackers overlay fake forms or modify page elements to phish credentials | Users unknowingly submit data to attacker-controlled elements |
| Malicious AI agents that abuse checkout flows | ✓ | ✗ | AI agents can automate fraud at scale across payment and signup flows | Without AI agent detection, automated abuse goes unchecked |
| Device level malware on user devices | ✗ Not a focus | ✓ | Endpoint malware intercepts data before it reaches the browser | No website-side security can consistently protect against malware already on the user's device. This falls outside what any website owner can technically guarantee |
| VPN/Proxy Detection | ✓ | ✗ | VPN and proxy use can indicate fraud, abuse, or geo-spoofing | Without detection, fraudsters hide behind anonymized connections |
| Data skimming scope | Payment Info, Forms, KYC flows | Payment Info | Skimming targets more than just card data; forms and KYC flows carry sensitive PII | Narrow scope leaves non-payment data unprotected from exfiltration |
Deployed on the application. Operates inside the browser session.
