Tenable Nessus / Tenable.io / Tenable One
World's most widely deployed vulnerability scanner — 80,000+ plugins, 30,000+ customers, the Cyber Exposure category-defining platform
Tenable's vulnerability scanner heritage starts with Nessus, the world's most widely deployed scanner, with 80,000+ plugins covering IT, OT, cloud and web application assets. Tenable.io is the SaaS continuous-VM platform built on the same engine. Tenable One consolidates VM, Cloud Security Posture Management, web application scanning, OT visibility and identity risk under one Cyber Exposure Score. For UAE enterprises with mature in-house VM teams, Tenable is the safest scanner-led shortlist option — at the cost of needing the operational capability to run it.

Why it wins
What makes Tenable Nessus / Tenable.io / Tenable One a serious option
Industry-standard scanner with broadest plugin library
Nessus is the world's most widely deployed vulnerability scanner. 80,000+ plugins cover virtually every asset type, OS, network device, web application framework and cloud configuration. Procurement and audit teams across UAE recognise the platform name.
Cloud-native continuous VM platform
Tenable.io is the SaaS-delivered continuous VM platform built on the Nessus engine. No on-prem infrastructure to operate, with full multi-tenant scaling and continuous discovery across hybrid estates.
Unified Cyber Exposure across VM + CSPM + WAS + identity
Tenable One consolidates vulnerability management, Cloud Security Posture Management, web application scanning, OT visibility and identity risk into one platform with a unified Cyber Exposure Score. Reduces tool sprawl for buyers consolidating multiple exposure categories.
Tenable OT Security for industrial environments
Tenable OT Security (formerly Indegy) extends visibility into OT and ICS environments with safe protocol-aware scanning. Useful for UAE energy, utilities and manufacturing estates with hybrid IT + OT scope.
VPR risk scoring beyond CVSS
Vulnerability Priority Rating (VPR) applies machine learning over exploit intelligence, threat actor activity and asset criticality to produce a prioritisation score that goes beyond raw CVSS. Helps in-house VM teams cut the noise from CVSS-only programmes.
Reference standard for procurement and audit
Tenable / Nessus is the reference standard most UAE audit and procurement teams recognise by name. Lowest risk profile of any scanner-led shortlist option for buyers prioritising vendor maturity and audit defensibility.
Who should put Tenable Nessus / Tenable.io / Tenable One on the shortlist
UAE large enterprises and banks with mature in-house VM teams
Estates with significant hybrid IT + OT scope (Tenable OT Security)
Organisations consolidating VM + CSPM + WAS + identity risk under Tenable One
Buyers prioritising scanner-led platforms with the broadest plugin library
Procurement-driven shortlists where vendor recognition is decisive
Customers who want to operate the platform themselves with optional managed wrapper
Multi-cloud estates needing native Tenable Cloud Security alongside VM
Product portfolio
Modules we deploy and manage
Picking the right SKU is as important as picking the right vendor. We size by asset count, audit obligations, OT scope and operational appetite, not by brochure tier.
What to consider
The honest watch-outs
Every platform has trade-offs. We would rather raise these now than have you discover them three months into a deployment.
Tool-led rather than service-led
Tenable is a platform you operate. Requires an in-house VM operations capability or a managed-service partner. UAE customers without dedicated VM engineers typically need to pair Tenable with managed-service delivery or pick a managed alternative like Sophos Managed Risk instead.
Premium pricing at the Tenable One tier
Tenable One bundle pricing is at the upper end of the market. Many customers start with Nessus or Tenable.io and grow into the broader Tenable One platform as exposure-category consolidation becomes a goal.
Best fit for mature VM teams
Tenable's value scales with the maturity of the team operating it. For lean mid-market security teams without dedicated VM engineers, Sophos Managed Risk's managed delivery typically produces better outcomes per dollar.

Frequently asked
Tenable Nessus / Tenable.io / Tenable One questions we hear from UAE buyers
Nessus Professional is the entry-point scanner — single user, manual scans. Tenable.io is the SaaS continuous-VM platform for organisations that have outgrown standalone Nessus. Tenable One is the unified exposure platform consolidating VM + CSPM + WAS + identity risk. Most UAE customers start with Tenable.io and grow into Tenable One as exposure-category consolidation becomes a goal.
Both are Gartner Leader-tier VM platforms. Tenable has the deepest plugin library (Nessus) and the strongest OT story. Qualys has the most integrated patch-management and policy-compliance bundle. For UAE customers with significant OT scope or where Nessus is already in use, Tenable typically wins; for cloud-first SaaS-only estates with bundled patch needs, Qualys often wins.
Yes — Tenable OT Security (formerly Indegy) provides safe protocol-aware scanning for OT and ICS environments. Critical for UAE energy, utilities and manufacturing estates with hybrid IT + OT scope. Tripwire Industrial Visibility is the alternative if Tripwire is already in the estate.
If you don't have dedicated VM engineers — yes. Tenable is a tool-led platform that needs operational capability behind it. Artiflex IT can deliver Tenable as a co-managed service, or we'll recommend Sophos Managed Risk if a fully-managed-outcome model is the better fit.
