Cybersecurityservices that find the gaps before attackers do.

We review your applications, cloud and network for weaknesses, fix what we find, and can monitor and respond to threats on an ongoing basis under a scope agreed with you.
Discuss your security

Many breaches don't start with clever hackers. They start with a leaked key or a weak login.

Exposed secrets, missing authorization checks, open storage and forgotten admin accounts are common and preventable. Our security work starts where these problems hide: in your code, your cloud setup and your access rules.

Why security falls behind in growing companies

01

Features win every sprint

Security work has no deadline until something happens, so it keeps moving to the next quarter.
02

Secrets in the wrong places

API keys and passwords end up in code, config files or mobile app bundles.
03

Weak authentication and authorization

Users can reach data or actions they shouldn't, because checks are missing on the server.
04

Cloud defaults left untouched

Open storage, broad permissions and unused accounts pile up in cloud environments.
05

AI-generated code nobody reviewed

Apps built quickly with AI tools often ship with exposed secrets and common OWASP issues.
06

Nobody is watching

Without monitoring, suspicious activity is noticed late or not at all.

Signs you need a security review

If any of these apply, a review costs far less than an incident.

1

A security questionnaire arrived

A large customer wants answers about your security, and you're not sure what to say.

2

Fundraising or acquisition is near

Investors or buyers will ask about security during due diligence.

3

Your app was built fast

An MVP, an AI-built app or an inherited codebase reached real users without a review.

4

Former staff still have access

Accounts and keys of people who left were never fully revoked.

5

You handle sensitive data

Payment, health, financial or personal data raises the cost of every mistake.

6

Something looked wrong

Unusual logins, unexpected cloud bills or odd traffic, and no one to investigate.

What we do

Security for your apps, cloud and network

Web app security audits

A review of your web application's code, APIs and configuration for vulnerabilities and weak authentication.

Checks of iOS and Android apps for exposed secrets, insecure local storage and unsafe API use.

Managed cloud security services

Ongoing review and hardening of your AWS environment: access, storage, network rules and logging.

Managed network security services

Configuration review and ongoing management of firewalls, network access and segmentation.

Managed detection and response

Monitoring for suspicious activity, investigation of alerts and response steps agreed with you in advance.

Access and identity reviews

Who has access to what, cleanup of stale accounts and stronger sign-in rules.

Remediation

Our engineers fix the issues we find, or work with your developers to fix them.

Security documentation

Clear records of your setup, access rules and incident steps for your team.

What a security audit of your app covers

Security audits of web and mobile apps focus on the weaknesses attackers find first.

Authentication and access

Login, session and password handling

Authorization checks on every endpoint

Roles and permission logic

Code and secrets

Exposed API keys and credentials

Common OWASP vulnerabilities

Outdated dependencies with known issues

Cloud and infrastructure

Exposed storage and databases

Permissions and unused accounts

Network rules and public endpoints

Findings you can act on

Issues ranked by risk

Steps to reproduce and fix

A retest after fixes

Who is this for

For companies without a security team

Startups

Your product grew fast and needs a review before larger customers or investors look closely.

Product companies

You have engineers, but nobody whose job is security.

SMBs

Your business runs on cloud tools and data you can't afford to lose.

Founders of AI-built apps

Your app works, but no one has checked how it handles keys, logins and user data.

Where do you want to start?

Audit an app

Web or mobile, code and configuration.

Secure the cloud

Review and harden your AWS setup.

Clean up access

Accounts, keys and permissions.

Set up monitoring

Detection and response for key systems.

Fix known issues

Remediation of findings from any audit.

Prepare for due diligence

Answers backed by a real review.

How a security engagement works

01

Scoping call

We agree which apps, environments and systems are in scope and what access we need.

02

Assessment

We review code, configuration, cloud and access, and test for the issues attackers look for first.

03

Report

You get findings ranked by risk, with steps to reproduce and recommended fixes.

04

Remediation

We fix the issues with your team or hand clear tickets to your developers, then retest.

05

Ongoing protection

If you need it, we monitor and manage security under a scope and response times agreed in your contract.

Why Gilzor

We build and maintain web and mobile products, so we review security the way a developer will have to fix it: with specific, code-level findings.

What we bring

Developers who fix

The team that finds an issue can also fix it in your code.

AI-built app experience

We take AI-built apps to production and know where they're usually weak.

Web, mobile and cloud

One team for your apps and the AWS setup behind them.

Fast start

Work can start in about two weeks.

On-time delivery

98% of our projects are delivered on time.

What makes us different

Findings, not fear

Clear, ranked issues instead of raw scanner output.

Honest scope

We tell you what we checked and what we didn't.

Fixes included

Remediation by engineers who already know your findings.

A named point of contact

One person who knows your systems and your risks.

Overlap with US hours

Our engineers in Europe overlap with part of the US working day.

What our clients
frequently ask

What do your cybersecurity services include?

Security audits of web and mobile apps, cloud and network security reviews, access and identity cleanup, remediation, and ongoing managed security with monitoring and response. You can start with one audit or a wider scope.

What does a security audit of a web or mobile app check?

Authentication and authorization, session handling, exposed secrets, common OWASP vulnerabilities, outdated dependencies, API security and the cloud configuration behind the app. You get findings ranked by risk with steps to fix.

What is managed detection and response?

Ongoing monitoring of agreed systems for suspicious activity, investigation of alerts and response steps defined with you in advance. Scope and response times are agreed in your contract.

Can you secure an app built with AI tools?

Yes. AI-built apps often have exposed keys, weak auth and missing server-side checks. Our light audit of an AI-built app takes 1–2 days and a full audit 3–5 days, followed by fixes if you want them.

Will an audit make us compliant?

An audit shows where you stand and what to fix, and its findings help with customer questionnaires and compliance work. It is not a certification or a compliance sign-off.

How is cybersecurity work priced?

Audits are quoted after a short scoping call. Managed security is billed monthly, based on the scope in your contract. Tell us what you want covered and we'll send a quote.

No sales pitch

Tell us what you want checked

Describe your apps, cloud setup and concerns. We'll suggest a scope for an audit or ongoing security, and a quote.

Next, a few optional questions so the first call is useful. We use your details only to reply to your request. Privacy Policy
