10 Best Pentest Companies in Brazil (2026) Compared

Comparing pentest companies in Brazil is hard because nobody does it honestly — every blog belongs to a company praising itself. This article is the exception: a direct comparison of the most relevant Brazilian pentest companies in 2026, including No Vuln, with objective criteria, price range, industry focus and when it makes sense to hire each one — whether you're a Brazilian company or a foreign one looking for a pentest provider in Brazil.

Disclosure: No Vuln (the author of this article) is included in the list. The criteria are applied equally. Where there's a conflict of interest, we flag it.

What are the top pentest companies in Brazil in 2026?

The 10 Brazilian pentest companies analyzed in depth in this article are: No Vuln, Tempest Security Intelligence, Cipher, Módulo Security, HackerSec, IntrusionCyber, LC Sec, Conviso, Protelium and Clavis. Two additional mentions round out the picture: Hakai Security and Tenchi Security. The Big Four (Deloitte, EY, KPMG, PwC) also offer pentesting, usually as a module of a larger external audit. International platforms (Synack, Cobalt) and top bug bounty researchers offering their services directly complete the options.

Each one has a distinct focus. There's no “best pentest company in Brazil” in the abstract — there's the best one for your situation: size, industry, applicable regulation, operating model and budget.

How to evaluate a pentest company

Before the list, here are the objective criteria that separate a serious company from one that sells a scanner as a pentest:

• Adversarial track record — do the researchers have findings in international programs (U.S. Department of Defense, eToro, Bitso, Hostinger, Synack)? Published CVEs? Talks at DEF CON, Black Hat, H2HC, BSidesSP?
• Industry focus — fintech, B2B SaaS, e-commerce, marketplaces and healthtech have different risk patterns. A company that “does everything” usually does little of it well
• Deliverables — an executive + technical report + a statement formatted for the auditor (SOC 2, ISO 27001, Resolution 4,893 (CMN 4,893) of Brazil's Central Bank (BACEN), PCI DSS QSA)?
• Retest included — in 2026, retesting is a commodity; charging extra for it is a red flag
• Direct contact with the researcher — do you talk to the person who found the bug, or only to an account manager?
• Operating model — one-off black box/white box, recurring sprint-aligned, or continuous PTaaS (Pentest as a Service)? Each one has a different fit

1. No Vuln

(Declared conflict — author of this article.)

• Focus: B2B SaaS, fintech, marketplaces, API security, e-commerce and growing startups. Also supports LGPD compliance (Brazil's data protection law) for companies in production
• Model: sprint-aligned continuous pentesting (PTaaS) + one-off pentests when the case calls for a fixed scope. Proprietary technology integrated with frontier AI models, led by researchers who validate every finding
• Track record: findings at the U.S. Department of Defense (Hack the Pentagon), eToro, Bitso and Hostinger
• Price range: hour-based packages — Sprint (25h, US$ 3,750 to US$ 6,250), Deep Dive (50h, US$ 7,500 to US$ 12,500) and Full Scope (100h+, from US$ 15,000), at US$ 150 to US$ 250 per hour. PTaaS (recurring): pricing on request
• Differentiator: methodology built in international bug bounty programs (U.S. DoD, eToro, Bitso, Hostinger); direct contact with the researcher (no account manager layer); retest included within 30–90 days; fast onboarding with a mutual NDA within 24h and a proposal within 3 business days; report formatted for LGPD Art. 46, SOC 2 (CC7.1) and BACEN Resolution 4,893
• When it makes sense: B2B SaaS, fintech, marketplaces, e-commerce or APIs that need real adversarial coverage (cross-tenant BOLA, OAuth ATO, race conditions, SSRF chains, JWT confusion), SOC 2 / BACEN / LGPD readiness, with an agile model (sprint-aligned or one-off) and a direct relationship with the researcher. Serves everything from early-stage startups to Series A+

2. Tempest Security Intelligence

• Focus: broad cybersecurity — pentesting, red team, AppSec, cloud, compliance, threat intel, SOC, MSSP
• Positioning: one of the largest Brazilian offensive cybersecurity companies; acquired by Embraer in 2020
• Price range: enterprise (budget quoted on request)
• Differentiator: scale; an established presence in Brazilian banks, telecom and critical infrastructure; strong coverage of Open Finance, PCI DSS and LGPD in large environments; capacity to take on multidisciplinary enterprise projects
• When it makes sense: large digital banks, fintechs at scale (unicorns), telecom, critical infrastructure, enterprise projects that need multiple services at the same time

3. Cipher

• Focus: SOC, enterprise pentesting, incident response, managed security for large companies
• Positioning: a traditional Brazilian company acquired by Prosegur, with a presence in large corporate environments
• Price range: enterprise
• Differentiator: the ability to run SOC + pentesting + incident response as an integrated package, global presence through Prosegur, a strong fit in industry, large retail and international operations
• When it makes sense: large companies that want a single end-to-end cybersecurity provider (not just pentesting)

4. Módulo Security

• Focus: governance, risk and compliance (GRC), pentesting and security in regulated environments
• Positioning: one of the historic security companies in Brazil, with an established presence in government, banks and critical infrastructure
• Price range: enterprise
• Differentiator: a long track record in regulated environments, its own GRC platform, a fit for projects where compliance and technical security need to be delivered together
• When it makes sense: public agencies, traditional banks, critical infrastructure, regulated companies that need GRC + pentesting from the same provider

5. HackerSec

• Focus: Pentest as a Service (PTaaS), AI-first, continuous platform, SaaS / startups
• Positioning: a modern continuous pentesting model via a platform with a real-time dashboard, combining AI with human validation
• Price range: mid-market (monthly subscription, SaaS model)
• Differentiator: a real-time findings dashboard, retest included, contact with the pentester via the platform, fast onboarding, a focus on products that change quickly
• When it makes sense: SaaS / startups that prefer a PTaaS model (continuous pentesting managed through a platform, with AI speeding up triage). An alternative to one-off pentesting when the product changes every week

6. IntrusionCyber

• Focus: red team, manual pentesting, OT/SCADA, adversary emulation
• Positioning: a technical offensive security company focused on advanced adversary simulation and industrial environments
• Price range: enterprise
• Differentiator: depth in long-running red team engagements, OT/SCADA coverage (industry, energy, oil & gas) that few Brazilian firms offer
• When it makes sense: companies that need advanced red teaming (exercises lasting weeks or months) or pentesting in industrial / OT environments

7. LC Sec

• Focus: web pentesting, LGPD, security consulting for SMBs and startups
• Positioning: a more affordable company in price and scope, a fit for growing companies
• Price range: mid-market to small business
• Differentiator: affordable pricing, serves companies moving beyond the MVP stage, a focus on operational LGPD compliance
• When it makes sense: SMBs or growing startups looking for a first pentest on a controlled budget, especially for LGPD compliance

8. Conviso

• Focus: continuous AppSec, DevSecOps, SAST/DAST, security in the SDLC
• Positioning: an AppSec platform (Conviso AppSec) + offensive security services
• Price range: mid-market to enterprise
• Differentiator: SDLC integration, proprietary tools for managing findings, a focus on sustaining continuous AppSec at companies with an active dev team and mature CI/CD
• When it makes sense: companies with a constantly evolving SaaS product and an active development team that need an AppSec platform integrated into the pipeline (not just one-off pentesting)

9. Protelium

• Focus: pentesting, vulnerability assessment, LGPD, corporate networks
• Positioning: a security consultancy with mixed coverage (corporate IT + applications)
• Price range: mid-market
• Differentiator: a presence in corporate networks and mixed environments (on-premises + cloud), a focus on operational LGPD compliance
• When it makes sense: companies with a significant corporate IT footprint (ERP, AD, networks) that need pentesting combined with LGPD compliance

10. Clavis Segurança da Informação

• Focus: offensive security, training, technical community
• Positioning: a traditional Brazilian security company, well known in the technical community and in CTFs
• Price range: mid-market
• Differentiator: a long-standing technical reputation, a strong community presence, a combined pentesting + training offering
• When it makes sense: companies that value a team with a technical community and CTF background, especially when training the in-house team is part of the scope

Other notable players

Hakai Security

A boutique offensive security consultancy with researchers active in CTFs and bug bounty. Mid-market pricing. A fit for companies that want technical depth without the overhead of a giant consultancy.

Tenchi Security

A niche player in cloud security and third-party risk management (TPRM), with its own tool (Zanshin) for vendor risk management. A fit for companies with a strong cloud footprint and an extensive SaaS supply chain.

Big Four / Big Five (Deloitte, EY, KPMG, PwC, BDO)

Pentesting comes as a module of a larger audit. Premium enterprise pricing. A fit when the pentest needs to line up with an external audit of another kind (financial, SOX, ISO). Tradeoff: the adversarial coverage is generally shallower than a specialized firm's.

Synack, Cobalt, BugSplat (international PTaaS)

Global pentest-as-a-service platforms with an international pool of researchers. A fit for global multi-product companies. Tradeoff: the relationship with the researcher is mediated by the platform, and local coverage of Brazilian regulation is weaker.

Top bug bounty researchers (direct service)

Top researchers from international programs offering their services directly. Price range: R$ 3k–R$ 15k per project. Maximum technical depth, but no institutional NDA, no auditor-ready report, no CNPJ (Brazilian company registration) to issue an NF-e (Brazil's electronic invoice), and no contractually guaranteed retest.

Traditional enterprise vs modern PTaaS: how the market splits today

In 2026, the Brazilian pentest market is clearly split into two camps:

• Traditional enterprise consulting — Tempest, Cipher, Módulo, IntrusionCyber, the Big Four. Model: one-off pentests, a defined scope, a formal report, enterprise clients. Strong in compliance (BACEN, ISO, SOC 2, PCI DSS), multidisciplinary red teaming and critical environments.
• Modern PTaaS / continuous pentesting — No Vuln, HackerSec, Conviso, LC Sec (and international platforms like Synack and Cobalt). Model: sprint-aligned monthly subscription, AI speeding up triage combined with human validation, retest included, fast onboarding, direct contact with the researcher. A fit for SaaS that ships every week, early-stage fintech, e-commerce, marketplaces and growing startups.

Several Brazilian companies are moving to the PTaaS model because an annual pentest is no longer enough — SaaS changes every sprint, and regulatory compliance keeps getting stricter. No Vuln has operated on this modern model from day one: proprietary technology integrated with frontier AI models, led by researchers who validate every finding; recurring and sprint-aligned; direct contact with the researcher (not an account manager); retest included; and fast onboarding with a mutual NDA within 24h.

No Vuln's specific differentiator within this group is its researchers' background in international bug bounty programs (U.S. Department of Defense — Hack the Pentagon, eToro, Bitso, Hostinger) — which delivers the adversarial depth usually associated with traditional enterprise consulting, now within an agile PTaaS model accessible to B2B SaaS, fintech, marketplaces and startups in Brazil.

How to choose yours: a 30-second decision tree

• Brazilian B2B SaaS, R$ 50k–R$ 500k MRR, with regulation (BACEN / SOC 2) → No Vuln, Conviso, Hakai, HackerSec
• Digital bank, critical infrastructure, enterprise fintech → Tempest, Cipher, IntrusionCyber, Módulo
• Early-stage startup, first pentest, tight budget → No Vuln (Sprint package), LC Sec, a top bug bounty freelancer
• A company that needs to pair pentesting with an external SOX / ISO audit → the Big Four (Deloitte, EY, KPMG, PwC)
• Strong cloud footprint + SaaS supply chain → Tenchi Security
• Global multi-product SaaS → Synack / Cobalt + a local firm for Brazilian regulation
• OT / SCADA / industrial environments → IntrusionCyber, Tempest
• Continuous pentesting via a platform with a dashboard → HackerSec, Conviso

Red flags in any pentest company

• Sells a “pentest” but the report only shows Nessus / Acunetix screenshots — that's a scan, not a pentest
• Charges extra for retests (a commodity in 2026)
• Has no researchers with a public track record (CTFs, bug bounty halls of fame, CVEs, technical talks)
• A generic report with no reproducible PoC
• Refuses a mutual NDA (you sign theirs, but they won't sign yours)
• No direct access to the researcher (account manager only)
• Guarantees “ZERO findings” — in 2026, every web application in production has at least one medium-severity finding; if they don't find one, they aren't looking
• A price below R$ 3,000 for a production system — almost certainly an automated scanner sold as a pentest

Conclusion

There's no “best pentest company in Brazil” in the abstract. There's the best company for your situation: size, industry, applicable regulation, budget, operating model.

If you're a B2B SaaS, an early-stage fintech, a marketplace or an API operating in Brazil that needs real adversarial coverage and a report formatted for SOC 2 / BACEN / LGPD, that's exactly No Vuln's niche. Compare 2 or 3 companies from the list above, ask for a detailed proposal, and see which one is the right technical and contractual fit for your team. Don't trust marketing claims — ask for anonymized PoCs of past findings, ask about the methodology in technical detail, ask for a sample report.
