Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
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
Transmit Security
- Pricing is not published, so it cannot be compared early against competitors that post per monthly active user rates, and the eventual quote often mixes per-user and per-transaction units.
- Migrating a live consumer identity base is a high risk project, and credential migration constraints mean some users must re-register, which shows up as measurable churn.
- The vendor is smaller than the identity incumbents, so the partner and systems integrator pool is thinner and staffing a large programme is harder.
- Workforce identity is not the focus, so an organisation wanting one vendor for employees and customers will still run two platforms.
- The fraud detection value depends on traffic volume feeding the models, so a smaller deployment gets less benefit from exactly the capability that justified choosing it over a plain identity provider.
