How Much Does Source Defense Cost? Plans and Limits
Source Defense is one of the few client-side security vendors that publishes its prices. This video walks through the four published tiers (as published in November 2026), what Source Defense does well (its sandbox and permissions model), the limits behind the headline price (payment-page caps, client-side security as a second product, Enterprise-only webhooks and API, support and retention), and how it compares with our published price for PCI DSS 6.4.3 & 11.6.1. We make Script Monitoring, so we're biased: every competitor fact comes from our comparison pages and is marked as something to check.
Full answer: Source Defense pricing
Transcript
Source Defense publishes its pricing. Essentials is $98 a month, billed annually, for 100,000 page views on one domain, and Enterprise is custom. We make Script Monitoring, so we're biased. Script Monitoring is one first-party tag on your payment pages that watches every script, in every session. As published in November 2026: Essentials, $98 a month. Standard, $197, for 250,000 page views and three domains. Professional, $315, for 500,000 and ten domains. Source Defense does a lot well. Its sandbox and permissions model constrains what a third-party script can do, rather than only watching it. It's a mature product with deep enterprise and QSA experience. What to check: payment pages are capped at two, five and ten when PCI Compliance is selected. Client-side security is a second product, added at a discount. And webhooks, the API and SIEM export are Enterprise only. Essentials and Standard include no human support, and Essentials keeps 30 days of data, so check that window with your assessor. And budget integration time: some vendor scripts need configuration inside a sandbox. Ours is published too. Pro is $99 a month for 100,000 payment-page views, a dollar more than Essentials, with unlimited domains and payment pages, both requirements in one price, and evidence packs kept 18 months. Above that, ours is $499 at 500,000, and $799 at a million. And there's a free plan under it. Source Defense offers a 14-day trial, not a free plan. So, choose Source Defense if you want to constrain what vendor scripts can do, and you have time to tune a sandbox. Choose us if you run several domains, and want to try it before talking to anyone. On every Script Monitoring plan, free included, you get a weekly PCI evidence pack for your assessor. Try it on your own checkout today. Script Monitoring is free for 1,000 page views a month, and Pro starts at $99 a month, with a 14-day trial. Start for free at scriptmonitoring.com.
