Penetration testing services that find what scanners miss.
SubRosa is a penetration testing company that finds and helps eliminate the vulnerabilities in your networks, applications, and infrastructure before attackers can exploit them, as a one-off engagement or penetration testing as a service (PTaaS).

Comprehensive testing across all attack vectors.
From network infrastructure to web applications, our team provides thorough penetration testing across every potential attack surface.
Network penetration testing
Identify vulnerabilities in your network infrastructure, firewalls, and internal systems before attackers can exploit them.
Learn more→Application security testing
Comprehensive web and mobile app testing to uncover SQL injection, XSS, authentication flaws, and business logic vulnerabilities.
Learn more→Social engineering
Test your team's awareness with phishing campaigns, vishing, and pretexting to identify human vulnerabilities.
Learn more→Wireless penetration testing
Assess the security of your wireless networks, identify rogue access points, and test encryption implementations.
Learn more→Physical penetration testing
Evaluate physical security controls including access badges, locks, surveillance systems, and on-site social engineering.
Learn more→Red team assessments
Full-spectrum adversary simulation combining multiple attack vectors to test your overall security posture and incident response.
Learn more→Cloud penetration testing
AWS, Azure, and Google Cloud tested for the IAM, storage, and configuration flaws unique to cloud.
Learn more→LLM & AI red team
Specialized adversarial testing for large language models and AI systems: prompt injection, jailbreaks, training-data leakage, and the failure modes unique to AI.
Find the way in before someone else does.
Attackers only need one gap. A penetration test surfaces the exploitable weaknesses across your network, apps, and cloud while you still have time to close them, ranked by real-world risk, not scanner noise.

Pass the audit, prove the controls.
SOC 2, ISO 27001, PCI DSS, and HIPAA all expect regular, independent testing. We map every finding to the controls it affects, so your evidence is ready when the auditor asks, not scrambled together the week before.

A breach costs far more than a test.
The impact of a breach reaches well beyond the immediate cleanup: downtime, legal exposure, customer churn, and brand damage. Proactive testing is a rounding error against that, and it is the difference between finding a flaw on your terms or theirs.

Testing with an attacker's mindset.
We think like adversaries
Our team doesn't just run scans. With backgrounds in offensive security, incident response, and threat hunting, we find what automated tools miss.
We test how attackers operate
Real attack paths and chained exploits, not just the checklist a compliance framework suggests.
We explain the business risk
Every finding includes potential financial impact, compliance implications, and clear, strategic recommendations.
We see it through
Testing is just the beginning. We work with your team through remediation, provide proof-of-concept patches, and re-test to confirm fixes hold.
Your pen test doesn't end in a report.
Every finding lands in Sable: assigned to an owner, tracked through remediation, and re-tested to confirm the fix holds. It turns point-in-time testing into penetration testing as a service (PTaaS), continuous visibility in the platform your team already works in, not a static PDF that goes stale the day it ships.
Findings

Common questions
- What is penetration testing?
- Penetration testing is an authorized simulated attack on your systems, carried out by security engineers who use the same techniques a real attacker would. The point is not to produce a list of theoretical weaknesses but to prove which ones are genuinely exploitable, chain them the way an adversary would, and show the actual business impact so remediation can be prioritized against real risk.
- How is a penetration test different from a vulnerability scan?
- A vulnerability scan is automated and matches your systems against a database of known issues. It is fast, cheap, and produces false positives and a long undifferentiated list. A penetration test is human-led: an engineer validates what a scanner flagged, discards the noise, and chains findings together to reach something that matters, such as turning a low-severity misconfiguration plus a weak credential into domain administrator.
- How much does a penetration test cost?
- It depends on scope: the number of IP addresses, applications, or physical sites in play, the depth of testing, and whether it is a point-in-time engagement or penetration testing as a service. Anyone quoting a price before understanding the scope is quoting for a scan. Send us your scope and we will price the engagement against it.
- How often should penetration testing be done?
- At minimum annually, which is what most frameworks and cyber insurers expect, and additionally after any significant change to what you expose: a new application, a cloud migration, a merger, or a material infrastructure change. A test describes your environment on the day it was run, so the sensible cadence is tied to how often that environment changes.
- What types of penetration testing does SubRosa perform?
- Seven attack surfaces: network, web and mobile application, wireless, physical, social engineering, cloud across AWS, Azure and Google Cloud, and full-spectrum red team assessments that combine them. LLM and AI system testing is also available for organizations shipping AI features.
