Threat & Vulnerability Management

Close security gaps before attackers find them.

Continuously identify, prioritize, and remediate vulnerabilities across your IT environments.
Threat & Vulnerability Management (1)

‘Fire drills’ alone won’t secure your business.

Tens of thousands of common vulnerabilities and exposures (CVEs) are published every year. Cloud environments drift the moment they’re provisioned. Web applications change with every release, and patches stack up. Internal teams tackle the most urgent needs and hope the rest aren’t critical.  

Now attackers are automating reconnaissance and exploitation, and AI tools are introducing entirely new attack surfaces. The lag between when a vulnerability is disclosed and when it is exploited is shrinking rapidly. 

In this environment, scanning alone isn’t enough. You need a prioritized, validated, and aligned program for surfacing and addressing your organization’s security risks and vulnerabilities.

The OnX approach

Find, fix, and validate.

OnX treats risk and vulnerability management as an operational discipline rather than a periodic project. Our approach blends three layers: 

1. Automated discovery, with continuous scanning across networks, endpoints, cloud, and applications to surface what’s changed and what’s exposed 

2. Expert validation by senior consultants and ethical hackers who separate the noise from the real risk

3. Prioritized remediation in a clear, business-aligned plan for what to fix first and what to monitor, backed by patch management and program-level reporting  

Our goal is to help you build a risk and vulnerability management program that gets stronger year over year.

Where to start

Advisory engagements

A CBTS advisory is a time-bound, fixed-fee engagement designed to give you a clear answer to a specific strategic question — fast.  

Cloud Migration Assessment & Wave Planning

Best for: Organizations facing a migration or re-platforming decision (including Broadcom/VMware-driven moves) that want a sequenced, dependency-aware plan before committing budget or moving workloads.

You walk away with:

  • Application inventory and dependency map across the migration scope
  • Per-workload assessment of the right destination (public cloud, managed infrastructure, or stay-put) and the right approach (rehost, replatform, modernize, or retire)
  • A wave-sequenced migration roadmap that orders the move from lower-risk proof workloads to complex interdependent systems
  • A defensible total cost model comparing current-state spend against projected future-state spend

What success looks like

 A working threat and vulnerability management program drives measurable business outcomes.

CBTS_IconSet_Green Duotone (6)

Reduced risk

 Eliminate exploitable vulnerabilities before they become incidents. Replace reactive scrambling with a governed program that closes the highest-impact gaps first.

CBTS_IconSet_Green Duotone (7)

Operational excellence

 Move from ad hoc scanning to a coordinated, repeatable discipline. Build the cadence, documentation, and reporting that satisfies audit, supports compliance, and matures year over year.

Frequently asked questions 

What’s the difference between vulnerability scanning and penetration testing? Vulnerability scanning is automated discovery. Software identifies known weaknesses across your environment and produces a list of CVEs to investigate. Penetration testing is human led, with ethical hackers actively attempting to exploit vulnerabilities to determine what an attacker could accomplish. Scanning tells you what’s potentially exposed; pen testing tells you what’s truly exploitable, how it would be exploited, and what the business impact would be. Most mature programs use both, with scanning running continuously and pen testing performed periodically for specific assets or compliance obligations.
How often should we run vulnerability assessments? Vulnerability scanning should run continuously. In fact, most OnX clients scan weekly or daily, with prioritization and reporting on a defined cadence. Formal vulnerability assessments (which add expert validation and roadmap development) typically happen quarterly or annually depending on environment volatility and regulatory requirements. Penetration testing is usually annual for the full environment, with targeted tests after significant changes (e.g., a major application release, cloud migration, or new acquisition).
What is AI ThreatCanvas, and how is it different from standard penetration testing? AI ThreatCanvas is an OnX offering built specifically for AI systems, such as LLMs, agents, and AI-integrated applications. Standard penetration testing focuses on infrastructure, applications, and APIs; it doesn’t account for AI-specific attack techniques like prompt injection, model extraction, training data leakage, or agent manipulation. AI ThreatCanvas tests against those techniques and others, surfacing the vulnerabilities that traditional security testing isn’t designed to find. It’s increasingly essential for organizations deploying customer-facing or internal AI systems.
How does OnX prioritize which vulnerabilities to remediate first?  We prioritize based on three factors: exploitability (is this genuinely attackable in your environment, or is it theoretical?), business impact (what does this vulnerability put at risk, and how badly?), and remediation effort (what does it take to fix?). The result is a working list that tells your team exactly what to fix first, what to monitor, and what can wait. Severity scores like CVSS inform our analysis but don’t drive it on their own.
Do you test cloud-native environments differently than on-premises environments? Yes. Cloud environments require different testing techniques and a different threat model. IAM misconfigurations, exposed storage buckets, over-permissive service accounts, and provider-specific architecture risks aren’t relevant in traditional on-premises testing. Our Cloud Security Assessment and cloud penetration testing engagements are scoped specifically for AWS, Azure, and GCP, benchmarked against provider best practices and CIS Cloud Foundations. For hybrid environments, we coordinate both approaches so nothing falls through the cracks at the boundary.
