Athera vs OpenVAS

Choosing the right vulnerability scanning solution today is no longer just about finding CVEs. Modern IT environments are distributed, hybrid, and constantly changing—spanning cloud workloads, remote offices, laptops, and closed networks. In this context, how a tool scans is just as important as what it scans.

In this blog, we’ll take a deep and practical look at Athera and OpenVAS, comparing them across architecture, deployment, scalability, usability, and real-world operational impact. 

What Is Athera?

Athera is a modern, cloud-native, agentless vulnerability scanning platform designed to eliminate the operational friction traditionally associated with vulnerability management.

Instead of tying scans to a single machine or complex network configurations, Athera enables organizations to:

  • Scan from the cloud
  • Use lightweight jump hosts for closed or segmented networks
  • Scale scans across multiple sites effortlessly
  • Operate without laptop lock-in or scanner sprawl

Athera is built for speed, simplicity, and enterprise-scale visibility—without sacrificing scan depth or control.

What Is OpenVAS?

OpenVAS (Open Vulnerability Assessment System), maintained by Greenbone Networks, is one of the most widely used open-source vulnerability scanners.

It is known for:

  • Strong vulnerability detection capabilities
  • A large and frequently updated vulnerability feed
  • Flexibility for security teams comfortable with self-hosting and manual configuration

However, OpenVAS was designed in an era where infrastructure was mostly on-premise—and that architectural legacy impacts how it performs in modern, distributed environments.

Architectural Comparison: Cloud-Native vs Self-Hosted

Athera: Designed for Distributed Environments

Athera follows a cloud-first architecture, meaning:

  • No dedicated scanning laptop or fixed scanner VM
  • Centralized management from a cloud console
  • Lightweight jump hosts to securely reach internal networks
  • Seamless scanning across multiple sites and regions

This architecture is ideal for organizations with:

  • Remote offices
  • Hybrid cloud infrastructure
  • Segmented or air-gapped networks
  • Remote workforce laptops

OpenVAS: Traditional Self-Hosted Model

OpenVAS typically requires:

  • Installation on a dedicated server or VM
  • Manual network routing, VPNs, or port forwarding
  • Separate instances for different sites
  • Ongoing maintenance of the scanner infrastructure itself

While powerful, this model introduces operational overhead as environments scale.

Deployment & Setup Experience

Athera focuses on time-to-value. Teams can start scanning quickly without worrying about OS hardening, feed synchronization, or scanner availability.

With OpenVAS, deployment is flexible—but that flexibility comes at the cost of setup time, tuning, and continuous maintenance.

Jump Hosts, Closed Networks & Multi-Site Scanning

Athera’s Strength: Native Jump Host Support

One of Athera’s standout capabilities is its lightweight jump host model:

  • No full scanner installation per site
  • No complex VPN or port-forwarding rules
  • One cloud-controlled scanning workflow across locations
  • Ideal for closed, segmented, or regulated environments

This makes Athera exceptionally well-suited for enterprises with:

  • Manufacturing plants
  • Branch offices
  • Secure internal networks
  • Compliance-driven segmentation

OpenVAS: Possible, but Not Native

With OpenVAS, scanning closed or remote networks typically requires:

  • Additional OpenVAS instances
  • VPN tunnels
  • Manual routing rules
  • More administrative effort per site

It works—but it’s not seamless.

Scalability & Operational Efficiency

Athera

  • Designed for horizontal scaling
  • Unlimited scanning without scanner sprawl
  • Central visibility across all environments
  • Configurable scan concurrency for performance control

OpenVAS

  • Scalability depends on infrastructure sizing
  • Multiple scanners = more maintenance
  • Concurrency tied to system resources
  • Scaling often means deploying more servers

For growing organizations, Athera’s model dramatically reduces operational complexity.

Scheduling, Automation & Control

Both platforms support scheduled scans, but the level of control differs:

Athera

  • Advanced scheduling
  • Configurable scan concurrency
  • Optimized for continuous scanning programs

OpenVAS

  • Scheduling supported
  • Concurrency control is limited and infrastructure-dependent
  • Requires careful tuning to avoid performance bottlenecks

Athera gives security teams predictable, controlled scanning at scale—without manual intervention.

Usability & Day-to-Day Experience

Athera

  • Clean, modern UI
  • Minimal operational overhead
  • Designed for security and IT teams alike
  • Faster onboarding and adoption

OpenVAS

  • Powerful but complex interface
  • Steeper learning curve
  • Better suited for experienced security engineers
  • Less friendly for non-specialist teams

If usability and speed matter, Athera clearly leads.

Cost & Resource Perspective

While OpenVAS is open-source, its true cost includes:

  • Infrastructure provisioning
  • Ongoing maintenance
  • Skilled personnel time
  • Scaling overhead

Athera replaces those hidden costs with:

  • A managed, cloud-based experience
  • Reduced infrastructure footprint
  • Lower operational burden
  • Faster security outcomes

For most organizations, this results in a significantly better return on investment.

Why Athera Is the Better Choice for Modern Enterprises

Athera isn’t just another vulnerability scanner—it’s a modern vulnerability scanning platform built for how organizations actually operate today.

Athera stands out because it offers:

  • Cloud-based, laptop-independent scanning
  • Native jump host and multi-site support
  • Agentless operation across closed networks
  • Centralized visibility with minimal effort
  • Enterprise-grade scalability without complexity

In contrast, OpenVAS—while powerful—reflects a traditional scanning model that struggles to keep pace with distributed, cloud-first environments.

Final Verdict: Athera vs OpenVAS

If your goal is simplicity, scalability, and modern vulnerability management, Athera is the clear winner.

OpenVAS remains a solid open-source scanner, but for organizations looking to reduce operational friction, scale securely, and future-proof their vulnerability management program, Athera delivers a more complete, enterprise-ready solution.
