Penetration testing with proven impact.
Web and mobile applications, infrastructure, cloud, devices and AI. Every finding is confirmed by exploitation, chained into a realistic attack path and rated on actual impact — senior specialists, standards matched to the target.
We secure the Czech tech companies that made it globally.
Penetration testing
Companies come to a penetration test for one of a few reasons: a customer or a tender requires it, a regulator or an audit requires it (NIS2, DORA, ISO 27001, PCI-DSS), a major release is going out, or something has already happened. In every case the deliverable is the same: a list of what an attacker could actually do in your systems, ordered by impact, with fixes.
Penetration testing at insighti is manual work by senior specialists. We do not hand over scanner output. Every finding is confirmed by exploitation, chained with others into a realistic attack path and rated by CVSSv3 on the impact we demonstrated, not on a tool's score. Methodology follows the target: OWASP OTG and ASVS for web applications and APIs, OWASP MASVS/MASTG for mobile, OWASP LLM and Agentic Top 10 for AI systems; infrastructure and cloud are tested as attack paths — what is reachable and where it leads.
What we test
What needs testing depends on where your business runs. Pick the target — each area states its scope and standards.
Web applications
Business logic, access control across roles, client-side code. OWASP OTG/ASVS, APIs included.
View scope
Mobile applications
iOS & Android, on the device and the backend.
View scope
Network & infrastructure
Perimeter to internal network — Wi-Fi, ICS/SCADA.
View scope
Red team
Test whether your team would actually detect and stop a real attacker.
View scope
Thick-client applications
Desktop apps — local data, memory, and backend.
View scope
Devices & IoT
Firmware, interfaces, and physical-access scenarios.
View scope
Cloud infrastructure
AWS, Azure & GCP — config, identity, and workloads.
View scope
AI & LLM applications
LLM apps, agents, RAG, MCP tools — what the model can reach and do. OWASP LLM & Agentic Top 10.
View scopeA penetration test tells you what's vulnerable. Whether your team would even notice the attacker — that's what a red team exercise tests. For DORA-regulated finance, the intelligence-led version is TLPT.
How much does a penetration test cost?
Price follows scope — the number of applications, roles and endpoints, hosts and services, or AI entry points — and the depth of the test (an OWASP Top 10 pass vs. full OTG, ASVS level L1–L3). Each area above states its scoping basis; we confirm the exact scope and price on a short call.
Use the test results toward NIS2, DORA, ISO 27001, and PCI-DSS.
Our insight.
The worst holes are rarely in the technology. A password reset built on a random, secret user identifier is sound — until the same identifier turns up in a fringe function of the system.
Frequently asked, always answered.
Do you test production systems, or should a separate instance be prepared?
Either. Production gives the truest picture; a staging instance allows more invasive testing without affecting users. We agree the approach before the start; on production we coordinate timing and your operations team is on standby during the test.
What is the difference between a vulnerability scan and a penetration test?
A scan finds known vulnerabilities by pattern; it cannot combine or exploit them. A penetration test is manual work: findings are confirmed by exploitation, chained into an attack path, and the real impact is demonstrated.
During testing, will any of our services be temporarily unavailable or data damaged?
The goal is not to disrupt service or damage data, and any potentially destructive test is agreed in advance. A system's reaction to an exploit cannot always be predicted, so we coordinate with your operations team and recommend current backups.
How do you scope a project and build a quote?
On a short call we walk through the environment with you — number of applications, roles, hosts or entry points — and propose a fixed scope and price. The call is free and non-binding.
Let's talk it through.
Tell us what you need tested — we'll set up a no-obligation call and propose a scope.
