Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
IDnow
- Agent-led video identification costs several times an automated check and depends on agent availability, so peak-time queues push abandonment up at exactly the moment conversion matters.
- Pricing is quoted with an annual volume commitment, so the accreditation advantage comes with a floor you pay whether or not you use it.
- The product is optimised for European regulatory regimes, so buyers verifying users in North America, Asia or Africa will find coverage and cost less competitive than global specialists.
- Qualified electronic signature is a separate licence from identity verification, which surprises buyers who assumed the accredited identity check made the signature capability included.
- Integration for the regulated flows is heavier than a simple SDK drop-in because the compliant journey, including consent and recording requirements, constrains the user experience you can build.
Nessus
- Nessus Professional is $4,790 for one year, with no free or low cost commercial tier
- Multi year terms are the only discount route, at $9,330.95 for two years and $13,637.54 for three
- It is a single user scanner, so team workflows mean migrating to another Tenable product
- Tenable One vulnerability management is priced separately, starting at $3,500 a year for 100 assets
