How Orca Security Compares to Tenable

A purpose-built platform to simplify cloud security

To secure the cloud, security teams want to easily onboard cloud accounts, quickly activate security capabilities, and avoid operational overhead from traditional, agent-based solutions–ensuring comprehensive coverage across the entire cloud tech stack.

With Orca Security, you benefit from a purpose-built Cloud Security Platform that addresses all of your cloud risks and features our patented SideScanning technology that covers your entire cloud estate, including AWS, Google Cloud, Azure, and Alibaba Cloud, without agents.

Tenable.cs, one of the offerings to address parts of security in the cloud, covers fewer cloud platforms, supports fewer cloud services, and is limited in its ability to see all of your cloud.  To see vulnerabilities across all cloud accounts & workloads means you’ll need additional subscriptions and you’ll have to deploy agents.

The agentless security pioneer

Orca’s patented SideScanning technology quickly and easily scans all of your Linux and Windows workloads, including cloud VMs, containers and Kubernetes applications, and serverless functions, without the need to configure scanners or network controls. This provides you with instant-on security and complete coverage for all your workloads and applications that Tenable.cs can’t match. Today, Tenable only provides an agentless assessment for AWS EC2 instances–and only 5 host operating systems–meaning most of your workloads won’t be covered, especially for advanced scenarios like FIM, log inspection, malware, and more.

A unified data model

The Orca Platform brings all of your data into a unified, easily-queryable location. With Orca’s Unified Data Model, you can view assets, compliance status, risks, and security incidents from one dashboard, rather than constantly hopping between different Tenable modules and offerings.

Comprehensive compliance for your entire cloud

Orca supports over 100 compliance frameworks, as well as our own Orca Best Practices and custom frameworks. This ensures that you can view compliance in a single dashboard and report covering your cloud infrastructure, data, identities, workloads, and more.  



Easy Onboarding

Simple 3-step activation model scans your cloud accounts, assets, workloads, data, and identities across multiple clouds without having to deploy agents

Difficult Activation and Optimization

Multi-stage activation includes onboarding users to multiple locations across multiple products across Tenable.cs, Tenable One, & Nessus and deploying agents to get vulnerability coverage across all assets

Asset Inventory


Continuously monitor public cloud services and configurations, entitlements and identities, workloads and applications, all from a single dashboard


Tenable.cs only supports 3 public clouds with agentless scanning only covering 5 operating systems on AWS EC2



100+ compliance frameworks with all data and policies shown in a single dashboard for seamless reporting


A limited number of frameworks that lack visibility across infrastructure, data, identities, and workloads

Attack Path Analysis

Automated and Interactive

Interactive dashboard, with automated impact score, surfaces toxic combinations of risks so teams can prioritize and fix the top 1% of issues. All risks mapped to the MITRE ATT&CK framework

Minimal Effectiveness

Attack paths are focused on on-prem scenarios with very limited cloud coverage. Requires additional subscriptions to Tenable One as well as,, and/or Nessus

PII Detection

Seamless and Comprehensive

Automatic detection of PII across all cloud resources

A Blind Spot

Tenable.cs focuses on cloud configuration and doesn’t scan data, thus lacking the ability to detect PII exposure or crown jewels

Malware Scanning


Signature and heuristic-based detection


A major blind spot for Tenable

Shift Left Security

Unified with Context

One CLI and dedicated Shift Left Dashboard for viewing all of your container image and IaC scans. Unified policy management of all your CI/CD policies

Fragmented Capabilities

Disintegrated capabilities from FlawCheck and Accurics. Lack of unified policy engine spanning code to runtime

API Security

Simple and Comprehensive

Automated inventory of all interconnected APIs and web domains. Capabilities integrated with agentless SideScanning technology, nothing new to activate. Prioritize risks, including external exposure, mapped to OWASP API Security Top 10 and contextualized with all other risks

Another Blind Spot

Even if you subscribe to all of the Tenable products, they lack integrated API scanning capabilities, leaving security teams with the challenge of identifying deployed APIs, detecting changes, and finding shadow API endpoints deployed
