Tenable review, pricing, features, pros & cons

Are too many vulnerabilities keeping your security team overwhelmed? Businesses often struggle because only about 3% of vulnerabilities are true exposures that hackers might actually exploit. Tenable One solves this by helping you identify and quickly eliminate those critical priority weaknesses across your entire attack surface.

āœØ

What is Tenable?

Tenable One is the world's leading exposure management platform, designed to unify security visibility across complex, modern environments. It's built for organizations that need a single, clear view of risk across disparate systems. The platform covers your entire attack surface, including IT infrastructure, cloud environments, operational technology (OT), identity systems, and even your emerging AI attack surface.

This comprehensive scope helps you move past security silos and focus on eradicating priority cyber weaknesses. šŸ’”

Tenable Key Features

šŸ’” Unified Visibility and Comprehensive Asset Inventory

It's hard to manage security when assets are scattered across different systems. Tenable One gives you a centralized, unified view of all your assets and associated risks. This inventory includes unseen, known, and emerging assets across your entire attack surface.

We connect asset and exposure data from your existing tools to enrich Tenable intelligence. This seamless connection helps reduce data redundancy and ensures integrity across the platform. You get a complete inventory reality, unifying multiple security silos into one coherent picture.

āœØ Predictive Prioritization for True Exposures

You don't have to fix every vulnerability; you only need to focus on the critical ones. Tenable leverages advanced, AI-driven insights to figure out which exposures attackers are most likely to exploit. This helps security teams quickly spot priority exposures that truly put the business at risk.

We use enhancements to our Vulnerability Priority Rating (VPR) to offer unmatched precision. By focusing only on these high-likelihood exposures, you efficiently eradicate priority cyber weaknesses. This strategy allows you to accelerate your overall exposure management efforts.

šŸ—ŗļø Dynamic Attack Path Mapping

Understanding how an attacker could breach your environment is crucial for prevention. The platform uses dynamic attack path mapping to visualize cross-domain relationships clearly. This helps you understand attacker accessibility through your network before a breach happens.

By seeing these relationships, you can identify and block your most critical attack paths. This proactive insight enables strategic mitigation, ensuring you take the necessary steps to secure high-risk infiltration routes.

āœØ Accelerated Mobilization and Remediation

Streamlining response is key to minimizing exposure time. Tenable One helps accelerate response with automated workflows and prescriptive guidance. This means your teams receive clear instructions on exactly how to close critical exposures.

The prescriptive guidance helps streamline overall remediation efforts. This capability allows your security teams to take rapid, decisive action to execute fixes and close security gaps quickly.

āœØ Broad Coverage Across the Modern Attack Surface

The modern attack surface includes much more than just traditional IT infrastructure. Tenable One unifies risk visibility across a wide range of environments. This includes systems that are often missed, such as operational technology and identity solutions.

We also introduce Tenable AI Exposure, leveraging generative AI to search for risks and amplify security expertise across your environment. This broad scope ensures you capture every element of risk in your converged network. The coverage areas include:

āœØ Advanced Analytics and Business Alignment

Effective communication about cyber risk requires clear, measurable data. Tenable One provides advanced analytics and reporting to streamline the measurement of cyber exposure. You can organize data to improve consistency and efficiency within your security program.

The platform uses business-aligned views to optimize decision making and investment strategy. These views help you identify and surface critical relationship context back to core business functions. This ensures your security efforts are always aligned with business outcomes.

Use Cases

āœØ Achieving True Clarity Across Your Attack Surface

Modern environments spread assets across complex, disparate systems. This often leaves security teams struggling to find everything across IT, cloud, and operational technology (OT). Tenable One provides a Comprehensive Inventory that combines all these asset domains. You gain a unified view of unseen assets, IT infrastructure, OT devices, cloud resources, and identity systems.

This unified view ensures you know your complete resource reality. Security teams move past silos, gaining high confidence that their entire attack surface is covered. Knowing all your assets is the vital first step toward effective exposure management. āœØ

šŸŽÆ Focusing Remediation on the Critical 3%

Your organization faces thousands of vulnerabilities, yet Tenable Research shows only about 3% are true exposures attackers are likely to exploit. It's challenging to know where to focus when everything feels urgent.

We provide clarity through advanced, AI-driven insights like enhancements to Vulnerability Priority Rating (VPR). This precision helps you prioritize the weaknesses that truly matter. By focusing only on the high-likelihood risks, you accelerate your remediation cadence and tackle the most business-critical issues first.

šŸ›”ļø Blocking Lethal Attack Paths Before They Start

Attackers rarely hit only one systemā€”they move laterally across the network. If your security visibility stops at the firewall, you miss these critical relationships. Tenable uses dynamic attack path mapping to visualize how threats could spread.

This platform clearly shows cross-domain relationships, like an identity exploit leading to OT access. You understand exactly how an attacker could move through your network before they have the chance. This insight allows you to surgically block the most critical attack paths and safeguard core business services.

āš™ļø Managing Risk in the Converged OT/IT Environment

For organizations running critical infrastructure, securely converging OT and IT environments is essential but complex. Operators need a holistic view that covers both domains. Tenable One acts as a unified security solution for these environments.

Approach Flow:

  1. Know every asset: See every physical and digital device across your converged environment from a single interface.
  2. Expose lethal gaps: Proactively identify weak points that threaten both IT assets and critical OT operations.
  3. Close priority exposures: Eradicate high-risk exposures specific to converged networks before they can be exploited.

ā±ļø Accelerating Response and Remediation

Discovery of a risk is essential, but execution defines success in cybersecurity. Security teams often get bogged down trying to coordinate fixes manually. Tenable streamlines remediation efforts with targeted steps.

You accelerate response times with automated workflows and clear, prescriptive guidance. This assures that remediation teams know precisely where to act and how. Your organization can take rapid, decisive action to close critical exposures and shorten mean time to remediation.

šŸ‘¤ Securing the Identity-Intelligent Enterprise

Identity systemsā€”Active Directory, hybrid, or Entra IDā€”are frequent entry points for attackers. You need a solution that unifies all user identities and flags exposure within that domain. Tenable helps you unify your complete identity reality.

It exposes top identity gaps and uncovers how identity risks might interact with and escalate cloud exposure. Teams can rapidly close security gaps with the highest likelihood of identity-based exploits. Finding and closing these exposures is crucial for protecting the enterprise.

šŸ§  Controlling the Emerging AI Attack Surface

As employees adopt generative AI platforms like ChatGPT and Microsoft Copilot, a new attack surface emerges that requires monitoring. Tenable introduces features to manage this evolving risk.

You can see how your employees are using these AI platforms across the organization. This visibility allows security teams to reduce AI-related threats and proactively manage risks across this quickly emerging domain.
