The short version

  • Only Tenable Nessus has a free tier, so it costs nothing to try first.
  • Each has a real cost: Tenable Nessus nessus Professional is $4,790 for one year, sold as an annual licence rather than a per scan or usage based fee; Trend Micro Vision One licensing is a credit pool consumed at different rates by different modules, so forecasting a renewal means modelling which capabilities you will activate rather than counting users, and switching on a new module silently draws down the budget for an existing one.
  • They diverge on capability: Tenable Nessus covers Network scanning, Trend Micro Vision One covers Cross-layer correlation.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Tenable Nessus

  • Nessus Professional is $4,790 for one year, sold as an annual licence rather than a per scan or usage based fee
  • Support beyond the base entitlement costs an extra $400 per year for Advanced Support with 24x365 phone and chat access
  • The on demand training course is a separate $275 purchase for a single person for one year
  • Multi year discounts require paying for two or three years up front

Trend Micro Vision One

  • Licensing is a credit pool consumed at different rates by different modules, so forecasting a renewal means modelling which capabilities you will activate rather than counting users, and switching on a new module silently draws down the budget for an existing one.
  • Retention in the XDR data lake beyond the included window is bought with additional credits, so the retrospective hunting the platform is sold on is precisely the part with an ongoing meter attached, and teams shorten retention to control spend.
  • The correlation that justifies the platform only exists over deployed Trend sensors, so an organisation running only the endpoint agent gets an EDR with a large console, and reaching the advertised value means a de facto single-vendor commitment across email, network and workload.
  • Legacy management planes persist: Apex Central, Deep Security Manager and the older Cloud One consoles overlap with Vision One and migrations have run for years, so administrators frequently maintain two consoles for the same agents and learn both.
  • The agents hook file and network operations, so on build servers, database hosts and developer machines the overhead is noticeable, and the standard remedy is broad path exclusions that remove protection from exactly the directories where attackers stage tooling.

Answered from the vendors’ own pages

Tenable Nessus: What are the three Nessus offerings?

Nessus Essentials is a free introductory offering for educators, students, and career starters, limited to 16 IPs for scanning. Nessus Professional is designed for consultants and SMBs, providing unlimited IT scans across any location. Nessus Expert is the premium offering extending Professional with web application scanning, infrastructure-as-code scanning, and external attack surface assessment up to 5 domains.

Source
Trend Micro Vision One: What are Trend Micro Credits?

A single purchased pool of licensing units drawn down by whichever Vision One modules you activate, at different rates per module and per protected object. It replaces separate per-product subscriptions and shifts the forecasting problem onto you.

Tenable Nessus: What OS platforms does Nessus support?

Nessus runs on Debian/Kali Linux, Fedora, FreeBSD, Mac OS X, Red Hat/CentOS, SUSE Linux, Ubuntu, and various Windows versions including Server 2008, 2012, and Windows 7-10.

Source
Trend Micro Vision One: Is this the same thing as Deep Security?

Not the same, but related. Server and workload protection in Vision One descends from Deep Security, and Trend has been migrating Deep Security and Cloud One Workload Security customers onto the Vision One platform. Existing Deep Security deployments still exist in the field.

Tenable Nessus: Can I use Nessus to scan third-party networks as a consultant?

Yes, Tenable permits you to use Nessus to scan third-party networks. Nessus Professional is ideal for consultants.

Source
Trend Micro Vision One: Does it replace my SIEM?

No. It correlates and retains telemetry from Trend sensors and selected third parties, but it is not a general-purpose log store for every system in the estate, and compliance log retention requirements are usually still met elsewhere.

Tenable Nessus: Can Nessus perform PCI external scanning?

Yes, you can use Nessus Professional to perform external network scans as required by the PCI DSS 11.2.2 requirement.

Source
Trend Micro Vision One: Do I have to use Trend endpoint protection?

To get real value, effectively yes. Third-party ingestion exists but the correlation quality depends on Trend's own sensor telemetry, and a Vision One deployment over someone else's endpoint agent is not what the platform is designed around.

Tenable Nessus: What additional features does Nessus Expert provide?

Web application scanning, which is dynamic application security testing (DAST) providing comprehensive visibility and insight into web application security issues; scanning code repositories for vulnerabilities; and assessing external attack surface with subdomain discovery.

Source
Trend Micro Vision One: Where is the data held?

In the regional instance you choose at onboarding. Confirm the specific region against your residency obligations before deployment, because moving afterwards is a migration.

Tenable Nessus: What support options exist for Nessus Professional?

Standard Support includes software upgrades, patches, plugin access, and 24x7 support via chat and community portal. Advanced Support adds 24x7 phone access and committed SLAs: P1 less than 2 hours, P2 less than 4 hours, P3 less than 12 hours, P4 less than 24 hours.

Source
Tenable Nessus: How frequently are Nessus plugins updated?

Nessus plugins are updated daily, based on when vendors and security research sites publish new vulnerabilities.

Source
Tenable Nessus: How does licensing work in virtual machine environments?

Whether you are using Nessus in a physical or a virtual environment, the IP addresses or hosts that you are scanning from must be licensed.
