Mercurius runs manual-led Red Team, penetration testing and cloud assessments that don’t just list vulnerabilities — they prove the exact path an adversary would take to your crown jewels, and how to close it.
Offensive security is the practice of testing an organization’s defenses by emulating real adversaries — actively finding, exploiting and chaining vulnerabilities to prove what an attacker could actually achieve. Unlike a vulnerability scan, which lists weaknesses in isolation, offensive security demonstrates attack paths: how an exposed asset leads to initial access, privilege escalation, lateral movement and, ultimately, a business-critical outcome. It spans penetration testing (scoped, technical depth) and Red Teaming (objective-driven adversary simulation that also tests detection and response).
From executive leadership to the slide your board actually reads — each capability stands alone or works as a single, mapped program.
Objective-driven, stealth-focused operations that emulate a real threat actor end to end — testing not just your controls, but whether your team detects and responds before a defined business objective is reached.
Internal and external testing of networks, applications and infrastructure with manual depth that scanners miss. Findings come with proof of exploitation and remediation guidance your engineers can act on.
Security assessments for web apps, mobile apps and APIs — business-logic flaws, authentication and authorization gaps, and the API risks that automated tools routinely overlook.
Identify and exploit misconfigurations and excessive privilege across AWS, Azure and Google Cloud — the IAM, exposure and lateral-movement paths that turn one weak setting into full compromise.
Every offensive engagement follows a defined, low-risk process agreed with your team before a single packet is sent.
Targets, objectives, allowed techniques, escalation contacts and safe windows agreed in writing.
Map the real attack surface — exposed assets, identities and entry points an adversary would find.
Find, exploit and chain findings to prove impact, with a live activity log and a defined stop procedure.
Executive and technical reports, findings rated by impact, mapped to your compliance frameworks.
Complimentary retest to confirm fixes hold — and a direct debrief with your security team.
Most providers bolt a pentest onto a defensive practice. We start from the attacker’s perspective. That means findings that reflect how breaches actually happen, validated by people who have run security on both sides of the table.
Our leadership and operators work across Brazil, Chile and the United States — so you get regional regulatory fluency and reporting in the language your team and board actually use.
A penetration test is a scoped, time-boxed assessment that finds and exploits as many vulnerabilities as possible in a defined target. A Red Team engagement is objective-driven and adversary-emulating: it tests whether your detection and response can stop a determined attacker from reaching a specific business outcome, using stealth and the full attack chain. Pentests measure exposure; Red Teams measure resilience.
Yes. Independent penetration testing is an explicit control in PCI DSS, supports the technical-measures requirements of LGPD and GDPR, and provides audit evidence for ISO 27001 and SOC 2. We format reports to map each finding to the relevant framework so they stand up in audit and board review.
Manual-led. Automated scanners are used for coverage, but every engagement is driven by experienced operators who chain findings, bypass controls and reproduce real attacker behavior. You receive validated, exploitable findings with proof of impact — not a scanner export full of false positives.
An executive report for the board and a technical report for your engineers, every finding rated by business impact and exploitability, reproduction steps, prioritized remediation guidance, and a complimentary retest to confirm fixes. We also debrief your security team directly.
Every engagement begins with a formal scoping and rules-of-engagement agreement defining targets, allowed techniques, escalation contacts and safe windows. Operators follow OSSTMM and OWASP methodologies, keep a live activity log, and have a defined stop procedure. Sensitive actions are coordinated with your team in advance.
Mercurius is offensive-led by design, operating in Brazil, Chile and the United States with delivery in Portuguese, English and Spanish. Our leadership includes a former CISO for Latin America at one of the region’s largest banks, so engagements are run by people who understand regulatory and board expectations across the region.
Tell us your environment and objective. We’ll come back with a scoping proposal and a recommended engagement — no obligation, no pressure.
