Whether you need to satisfy compliance requirements, respond to a board-level security mandate, or build a security team faster than your hiring timeline allows, Caliber has delivered for organizations like yours for over 15 years.
For organizations that need to validate the security of their network infrastructure and systems, whether for compliance, board reporting, or peace of mind.
Manual, expert-led penetration testing across your internal, external, wireless, and cloud networks. Our engineers map the paths an attacker would actually use, probing firewalls, switches, servers, and workstations for the weaknesses that matter: misconfigurations, out-of-date software, missing patches, weak protocols, command injection, and more. Automated scanning alone misses too much, so we pair it with hands-on manual testing to give you the full picture, not a partial one.
An executive summary your board can read, and a technical findings document your team can act on. Every finding is prioritized by real-world risk and paired with a clear remediation path, so you know what to fix first and how, before an attacker finds it for you.
"Caliber is easy to work with, responsive, and highly capable. They are more than a security company, they've been a trusted partner."
For organizations that build or rely on web, mobile, and desktop applications, or SaaS platforms that process and store sensitive data, and need to know those applications can stand up to a real attack.
Manual, expert-led testing of your applications against the OWASP Top 10 and beyond. Our application security consultants go after the flaws attackers actually exploit: SQL injection, cross-site scripting, broken authentication, misconfigured security controls, and the rest. We test web, mobile, desktop, and SaaS environments the way a real adversary would, not with a scanner alone. Where a vulnerability scan fits, we run it and then interpret the results, because a raw scan that flags everything equally tells you nothing about what to fix first.
An executive summary your board can read, and a technical findings document your team can act on. Every finding is prioritized by the real risk it poses to your organization, paired with clear remediation steps tailored to your environment. Each report also includes step-by-step walkthroughs to reproduce the findings, so your team can understand each issue and confirm the fix actually worked.
For organizations shipping code on a regular cadence that need their web applications watched continuously, not just tested once a year, so new vulnerabilities surface as they're introduced rather than months later.
Continuous, automated security testing of your web applications, powered by Burp Suite Enterprise. Caliber DAST scans on the cadence that fits how you build: daily for fast-moving teams shipping frequently, weekly for a steady pulse that won't slow development, or monthly for applications that change less often. It surfaces the issues that put applications at risk, including injection flaws, broken authentication, broken access controls, and outdated components, and it integrates into your development cycle so problems get caught early instead of in production.
A live dashboard giving your security and development teams one centralized view of every scan: real-time findings, risk levels, and remediation guidance, with trends tracked over time. Findings are prioritized by risk, not dumped in a list, so your team always knows what to address first and can coordinate fixes without guessing.
For organizations that need ongoing visibility into their vulnerability posture, for internal teams or to support channel partner clients.
TrustPlus, Caliber's vulnerability management platform built on Nessus, providing continuous scanning and a dashboard view of risk over time.
A living view of your environment's risk, not a static report that's outdated the week after delivery.

When your team has a gap, whether from a departure, a surge in project work, or a new compliance requirement, the wrong hire costs more than the delay. Caliber places vetted security professionals who are ready to contribute from day one.
We learn the gap, the timeline, and what success looks like.

"Caliber placed a senior application security engineer within two weeks of an unexpected departure, with zero gap in our testing cadence."
For organizations building or deploying generative AI and large language model applications that need to know their AI systems can't be manipulated, leaked from, or turned against them, before they put those systems in front of customers or sensitive data.
Manual, expert-led testing built for the way AI systems actually fail, guided by the OWASP Top 10 for LLM applications and generative AI. Our AI security consultants go after the risks unique to these systems: prompt injection, model poisoning, data leakage, insecure APIs, and weak isolation between tenants. This is a fast-moving attack surface most testing firms aren't equipped for, and we test it the way a real adversary would.
An executive summary your board can read, and a technical findings document your team can act on. Every finding is prioritized by likelihood and real-world impact, paired with remediation steps tailored to your environment. Each report also includes step-by-step walkthroughs to reproduce the findings, so your team can understand each issue, validate the fix, and harden your AI posture going forward.
For organizations whose security depends on locks, doors, and badge systems actually holding, and who need to know whether someone could walk in and bypass all of it without leaving a trace.
Real-world physical intrusion testing using the same techniques an actual attacker would. Our experts test your locks and door mechanisms with under-door tools, lockpicks, shims, and shove knives, and probe your access control system by cloning employee badges to see how easily a counterfeit credential gets someone through the door. The goal is simple: find the ways in before someone with bad intent does.
A detailed, actionable report documenting exactly where your physical defenses gave way, with prioritized recommendations to close those gaps. Findings from this kind of testing can be sensitive, so we contextualize them with you directly and keep discretion at the front of the process throughout.
That's what the first conversation is for. No pitch, just a direct conversation about where your gaps are.
Test the Human Layer Before an Attacker Does
For organizations that have invested in technical defenses but know their people are the surface attackers go after first, and need to see how their team actually holds up against a real social engineering attempt, not a checkbox awareness course.
Real-world social engineering testing across the channels attackers actually use. Remotely, we run targeted phishing emails and voice-based vishing calls that mimic the sophistication of a genuine attack, not generic test bait. On-site, our team simulates the physical approaches that get intruders through the door: tailgating, badge cloning, impersonating employees, vendors, or visitors, and the persuasive pressure that talks people past their own instincts. Every scenario is tailored to your environment, because the realistic ones are the ones that tell you something true.
A detailed, actionable report showing exactly how your team responded and where the gaps are, with clear guidance to strengthen training, tighten physical controls, and close the human vulnerabilities that technology alone can't. You get a real read on your organization's risk profile, not a participation score.
