Security audit for applications and infrastructure

Cybersecurity audits from Guadalajara, Mexico for companies in the US and Mexico

WITS runs security audits for companies in Mexico and the United States that build or depend on software and the cloud. We review five fronts (cloud, repositories, servers, application and continuity), fix what we find and prove it: the same audit engine measures before and after, control by control. We're based in Guadalajara, Mexico, in the same time zones as the US.

Who it's for

Does your company depend on software and cloud nobody has reviewed?

This service is for companies that build or depend on cloud software: agencies, SaaS, e-commerce and teams with their own systems. We come from custom software development, so we look at security the way a team running production systems lives it. Signs it's time to start:

  • 01Nobody knows for sure who has access to the cloud account, the server or the repositories.
  • 02There are credentials in the code, in emails or in a shared file.
  • 03Backups exist, but nobody has ever tried restoring them.
  • 04The server has open ports that nobody remembers opening.
  • 05The previous vendor left and the infrastructure was never documented.
  • 06A client or partner asked for security evidence and there's nothing to hand over.
Why WITS

Consultancies hand over a PDF. We fix it and prove it.

We don't sell loose technical tasks. The goal is to reduce the attack surface and keep an incident from happening again, with a scope you can measure.

The audit runs on a platform of specialized AI-powered agents, integrated with your organization's current tools, and an automated audit engine that produces measurable evidence before and after every remediation.

How we work

How does it work? Three phases: diagnose, fix and follow up

Each phase is contracted separately. You can start with the diagnosis only.

01 · Diagnosis

Security Assessment

We audit your cloud, repositories, servers and application, find the risks and rank them by impact. It's a fixed-price project.

Deliverables
  • Executive report
  • Risk matrix
  • Prioritized findings, with evidence
  • Remediation roadmap
  • Initial baseline, control by control
02 · Fixing

Security Remediation

We implement the prioritized fixes: access, configuration, hardening and code. Then we run the same audit again to prove the change.

Deliverables
  • Fixed environment
  • Post-remediation baseline
  • Before/after comparison: improvements and regressions
03 · Follow-up

Security Care

A monthly plan to keep the posture: infrastructure changes, people come and go, new vulnerabilities appear.

Deliverables
  • Monthly review of changes and access
  • Light audit of cloud, repositories and backups
  • Report compared against the baseline
What we review

Five fronts, in the order an attack happens

We start with the cloud account, the key to everything, and finish with the ability to recover.

  1. 01

    Cloud security

    The cloud account is the key to everything else. We review who gets in, with which permissions, and what is exposed.

    How exposed is your AWS infrastructure
  2. 02

    Repository security

    Code and its secrets live in the repository. We review how it's protected and who can change it.

  3. 03

    Server hardening

    What the server exposes to the internet and how people get into it.

  4. 04

    Application security

    We review the application's code against the most common web risks.

  5. 05

    Business continuity

    What happens if you need to restore. We check whether backups work and who is responsible.

Evidence

How do you prove security improved?

With a baseline. During the Assessment the audit engine records the state of every control. After remediation the same audit runs again and both results are compared: what improved, what's still pending and whether anything regressed.

What it isn't

What this service doesn't include

  • We're not a SOC and we don't offer 24/7 monitoring.
  • We don't certify ISO 27001: we identify gaps; certification is granted by an accredited body.
  • We don't sell a standalone black-box pentest: we review configuration, code and processes, and we fix what we find.

Review and drafting of legal documents is done with the support of legal specialists. WITS identifies needs and risks, but does not provide legal services.

Investment

How much does a security audit cost?

The diagnosis has a fixed price, agreed after a short scoping call. The rest is sized from what the diagnosis finds: closing five findings doesn't cost the same as closing fifty.

Security Assessment
Fixed price

Fixed-price project, quoted after a short scoping call. Prioritized findings, remediation roadmap and initial baseline.

Security Remediation
Quoted after the Assessment

Based on the prioritized findings and the roadmap. Includes the before/after comparison.

Security Care
Quoted after the Assessment

Monthly plan based on infrastructure size and pace of change.

Each phase is quoted at a fixed price in USD, or ongoing work as a dedicated monthly plan; for companies in the US we invoice in USD. You know what each phase costs before it starts.

Frequently asked questions

What companies ask before auditing their security

What is a security audit for companies?

It's a review of a company's cloud, repositories, servers and applications to find excess access, insecure configuration, exposed secrets and untested backups. At WITS it ends with prioritized findings, a remediation roadmap and an initial baseline against which improvement is measured.

How much does a security audit cost?

The Security Assessment is a fixed-price project, quoted after a short scoping call; for companies in the US we invoice in USD. Remediation and the monthly plan are quoted after the Assessment, because they depend on how many findings there are and how large the infrastructure is.

How is it different from a pentest?

A pentest simulates an attack at a point in time and reports what it achieved. We review cloud configuration, repositories, servers, code and continuity, prioritize by risk, and also implement the fixes, with before/after evidence.

What do you deliver at the end of the Assessment?

An executive report, the risk matrix, prioritized findings with their evidence, the remediation roadmap and the initial baseline: the state of every reviewed control, used to compare after fixing.

How do I know remediation actually improved security?

Because when we finish we run the same audit again and compare the result against the initial baseline, control by control. The comparison shows what improved and whether anything regressed; it isn't an opinion, it's the same measurement repeated.

Do you do ISO 27001 certification or 24/7 monitoring?

No. We're not a certification auditor or a SOC. We identify gaps and fix them. Legal documents, such as policies or privacy notices, are reviewed with the support of legal specialists: WITS identifies needs and risks, but does not provide legal services.

What happens after the fixes?

With Security Care we review infrastructure changes, new access, repositories and backups every month, and deliver a report compared against the baseline so the posture doesn't degrade over time.

Do you work with companies in the United States?

Yes. WITS is based in Guadalajara, Mexico, and works with companies in Mexico and the United States, in the same time zones. The audit is done remotely, with access agreed with you.
