The difference between Tenable and Wiz comes down to what each tool was built to protect. Tenable watches your whole attack surface, from aging servers in a back-room closet to cloud workloads and user identities.
Wiz zeroes in on the cloud, mapping risk across the platforms where modern apps actually run. Both are respected names, but they solve different problems. Picking the wrong fit wastes budget and leaves holes an attacker will happily walk through.
This guide breaks down how the two stack up in 2026, what changed after Google bought Wiz, and which platform suits which kind of team.

Tenable is a public cybersecurity firm known for finding weak spots before attackers do. It grew up around vulnerability management, and its Nessus scanner remains one of the most widely used tools of its kind. If you want a quick primer on the company and its history, this plain-language explainer on what Tenable is sets the stage well.
Today the company sells Tenable One, an exposure management platform that pulls many products under one roof: vulnerability management, cloud security, identity exposure, web app scanning, attack surface management, and OT security.
It ties all that data together to show which flaws pose the biggest risk to your business. Tenable Research feeds the engine with fresh threat data, and the newer Tenable Hexa AI layer automates routine work.
Tenable also pushed into fresh territory in 2025. At Black Hat USA that August, it launched Tenable AI Exposure, a tool for spotting risk in workplace AI apps such as ChatGPT Enterprise and Microsoft Copilot. The company now reports around 44,000 customers worldwide, which tells you it has deep roots across many industries.
Wiz is a cloud security platform built for the age of AWS, Azure, and Google Cloud. It sells a cloud-native application protection platform, or CNAPP, that scans an organization's entire cloud footprint and connects three layers into one picture: the code developers write, the cloud it runs on, and the workloads doing the work at runtime.
This "code to cloud" view helps teams see how a small misconfiguration can chain into a real breach.
Wiz grew at a blistering pace. It crossed $1 billion in annual recurring revenue in 2025, and roughly half of the Fortune 100 use it.
That growth caught Google's eye. After Wiz turned down a $23 billion offer in 2024, Google came back and closed a $32 billion all-cash deal on March 11, 2026, the largest purchase in Google's history.
Wiz now sits inside Google Cloud but keeps its own brand and, notably, its promise to protect customers on rival clouds like AWS, Azure, and Oracle Cloud.
The short version: Tenable is broad, Wiz is deep in the cloud. Here is how that plays out.
Tenable tries to see everything. Its platform reaches IT infrastructure, operational technology, IoT devices, cloud resources, containers, web apps, and identity systems. That width matters if your business runs a mix of old and new, say a factory floor full of OT sensors plus a fleet of cloud servers.
Wiz stays laser-focused on the cloud. It does that one job with real depth, mapping the toxic combinations of exposure that lead to cloud breaches. If your whole world lives in AWS or Azure, that focus is a strength, not a limit.
Wiz runs agentless. It connects to your cloud accounts through APIs and builds a risk map without installing software on every workload. Setup is quick, and there is little to maintain.
Tenable leans on scanners and agents, the classic Nessus model, though it added agentless cloud coverage too. Agents give you close-up detail on each machine, which pays off for on-prem and hybrid gear that cloud-only tools cannot reach.
Here is a fresh wrinkle in the Tenable vs Wiz debate. Now that Wiz belongs to Google Cloud, some buyers worry it may tilt toward Google's roadmap over time, even with the multicloud promise in place.
Tenable, as an independent public company, answers to no single cloud provider. For shops that want a neutral referee, that independence is worth weighing.

Neither company posts one flat price, since enterprise deals depend on the size of your setup. Nessus Professional sells as a yearly subscription, and buyers save by locking in a multi-year term. The wider Tenable One platform and Wiz both use custom quotes based on your asset count and cloud footprint.
If you want to compare tiers and see what fits your budget, this rundown of Tenable pricing plans lays out the options in one place. As a rough rule, Wiz tends to land in enterprise price ranges, while Tenable offers a wider ladder that starts with the modest Nessus scanner and climbs to the full platform.
Your answer hinges on where your risk lives.
Pick Tenable if you run a mixed shop with on-prem servers, OT or IoT gear, and cloud, and you want one view of the whole thing. It also wins for teams that value a vendor with no cloud-provider ties.
Pick Wiz if your business runs mostly in the cloud, especially across several providers, and you want fast, agentless coverage with sharp attack-path mapping.
Some teams run both. Tenable handles the wider estate while Wiz drills into the cloud. That combo costs more, so weigh it against your budget.
Cost stops many small teams from trying enterprise-grade tools. The good news is that Tenable's entry-level Nessus scanner is affordable enough for solo pros and students, and it teaches skills that carry over to the full platform.
Deal hunters can also sign up for the Nessus Black Friday newsletter deal to catch the yearly discount window instead of paying full sticker price.
Wiz, by contrast, rarely shows up in bargain-bin territory, since it aims at larger cloud budgets. So if price is your first worry, Tenable gives you a gentler on-ramp.
Is Wiz better than Tenable? Neither is flatly better. Wiz is stronger for pure cloud security, while Tenable covers a wider range of assets including on-prem and OT. The right pick depends on your setup.
Does Tenable do cloud security like Wiz? Yes, Tenable One includes cloud security and a CNAPP with identity coverage. Wiz still tends to go deeper on cloud-only, agentless mapping, which is its home turf.
Did Google really buy Wiz? Yes. Google closed the $32 billion all-cash deal on March 11, 2026. Wiz joined Google Cloud but kept its brand and its support for other clouds.
Can I use Nessus without buying the whole Tenable platform? Yes. Nessus is sold on its own, separate from Tenable One, which makes it a friendly starting point for smaller teams.
