Security Services Built for the Stakes You're Carrying

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.

Network & Systems Penetration Testing

Know Exactly Where Attackers Would Get In, Before They Do

Who this is for

For organizations that need to validate the security of their network infrastructure and systems, whether for compliance, board reporting, or peace of mind.

What we deliver

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actually use, probing firewalls, switches, servers, and workstations for the weaknesses that matter: misconfigurations, out-of-date software, missing patches, weak protocols, command injection, and more.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.

What you get

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.

Application Security Testing

Your Applications Are Where Attackers Look First. We Test Them Like One.

Who this is for

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.

What we deliver

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.

What you get

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.

Caliber DAST

Your Application Is Your Biggest Attack Surface. We Prove It.

Who this is for

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.

What we deliver

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.

What you get

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.

TrustPlus

Continuous Vulnerability Management, Not a Once-a-Year Snapshot

Who this is for

For organizations that need ongoing visibility into their vulnerability posture, for internal teams or to support channel partner clients.

What we deliver

TrustPlus, Caliber's vulnerability management platform built on Nessus, providing continuous scanning and a dashboard view of risk over time.

What you get

A living view of your environment's risk, not a static report that's outdated the week after delivery.

Generative AI / LLM Security Testing

Security Testing for the Systems Your Traditional Vendor Doesn't Understand Yet

Who this is for

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.

What we deliver

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.

What you get

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.

Social Engineering

Test the Human Layer Before an Attacker Does

Who this is for

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.

What we deliver

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.

What you get

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.

Physical Security Assessments

Find the Gap Before It Walks Through Your Front Door

Who this is for

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.

What we deliver

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.

What you get

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.
