Frequently asked questions
Penetration testing shows you how an attacker would exploit your system — before they get the chance.
It’s not just about checking a box. A proper pentest gives you a real-world view of your risks: where sensitive data could leak, what could take your platform offline, and which gaps might trigger a compliance failure.Whether you're scaling a digital health product, storing genomic data, or handling payments — penetration testing helps you:
-
Catch vulnerabilities before they’re exploited
-
Build trust with partners, investors, and customers
-
Meet requirements for HIPAA, GDPR, ISO 27001, and more
-
Ship faster by fixing the right things early
We go beyond automated scans. Our engineers test like real attackers, then help you fix like product teams.
Learn more about Pentesting here.
-
At a minimum, once per year — but frequency depends on your risk, product velocity, and regulatory needs.
We recommend testing:
-
Annually, as a baseline
-
After major code or infrastructure changes
-
Before launching new features or integrations
-
During compliance audits (HIPAA, GDPR, MDR/IVDR, ISO 27001)
-
If you’re onboarding enterprise clients or handling sensitive data
For high-risk sectors like biotech, healthtech, or fintech, a combination of continuous testing and annual deep dives is ideal.
Not sure what cadence is right? We’ll help you map your product roadmap to a realistic security
-
Vulnerability scanning is automated. It checks your systems for known issues, like outdated software or exposed services, and generates a list.
Penetration testing is manual and strategic. A security expert actively simulates real attacks to exploit weaknesses and see what’s actually at risk - like accessing user data, bypassing authentication, or moving laterally inside your system.
A good security program uses both; scans for ongoing hygiene, and pentests for risk validation and stakeholder assurance.
Penetration testing can be categorized by both the target and the level of access provided. Common target types include:
-
Network Penetration Testing: Assesses internal and external network infrastructure for misconfigurations, insecure services, or vulnerabilities.
-
Web Application Testing: Focuses on identifying security issues in web-based software, such as authentication flaws, injection vulnerabilities, and access control misconfigurations.
-
Mobile Application Testing: Evaluates mobile apps for insecure storage, improper permissions, weak encryption, and backend API exposures.
-
Social Engineering Testing: Simulates phishing, pretexting, or other tactics to test the human element of your security.
Penetration tests are also categorized by the level of information shared:
-
Black Box Testing: The tester has no prior knowledge of the systems, simulating an external attacker.
-
White Box Testing: Full internal knowledge is provided, such as source code and architecture documentation, simulating an insider or well-informed adversary.
-
Gray Box Testing: A hybrid approach where the tester has partial knowledge, offering a balance between realism and depth.
Each type offers different insights, and together they form a complete picture of your organization's security posture.

OWASP (Open Web Application Security Project) is a nonprofit organization dedicated to improving the security of software. It’s best known for the OWASP Top 10 — a regularly updated list of the most critical web application security risks, such as broken access control, injection vulnerabilities, and security misconfigurations.
At Sekurno, we use OWASP standards as a baseline in every application penetration test. It helps ensure your product isn’t just secure in theory — but resilient against the most common and dangerous real-world threats.
Whether you're preparing for a compliance audit or just shipped a new release, aligning with OWASP is a smart and essential step in reducing application risk.
No, ethical hackers will work closely with you to ensure that testing does not impact your regular operations or service availability.
‘White box’ testing is when the tester has knowledge of the internal structures or workings of the application. ‘Black box’ testing is done without any prior knowledge of the infrastructure.
We follow established security frameworks like OWASP and PTES to ensure every engagement is thorough, controlled, and safe. All testing is conducted in isolated, authorized environments to prevent data leakage, service disruption, or impact to production systems.
Every step, from scoping to reporting is handled by experienced security engineers who understand the importance of minimizing risk while uncovering real vulnerabilities.
We also coordinate closely with your team to define clear testing windows, communication channels, and rollback procedures if needed. Responsible testing isn’t just about finding issues, it’s about protecting your operations and earning trust along the way.
Our detailed report provides an executive summary for management, technical findings, a threat model document, and a checklist of all tests performed.
The cost of penetration testing varies based on scope, complexity, and type. However, considering the potential loss from a security breach, it’s a worthy investment for businesses.
Yes — but with limitations. Internal teams can perform basic security checks and even formal tests if they have the right expertise. However, internal testing often lacks the objectivity and specialized tactics of a dedicated offensive security team.
External penetration testers bring:
-
Unbiased assessment — no internal blind spots or assumptions
-
Up-to-date techniques — based on real-world attacker behavior
-
Broader experience — from testing across industries and architectures
-
Credibility for audits and clients — especially for compliance and due diligence
At Sekurno, we often work alongside internal teams, offering deeper, adversarial testing that complements in-house efforts. For high-risk industries or regulated environments, external testing isn’t just helpful, it’s expected.
-
-
Yes. Sekurno provides a third-party attestation letter confirming that penetration testing was performed by our expert team, along with a verifiable badge you can display on your website or share with clients.
-
The badge links directly to a hosted attestation letter, which outlines the scope, methodology, and date of the engagement — without disclosing sensitive details. It’s designed to build trust with partners, customers, and regulators by showing you take security seriously and have engaged an independent, credible testing team.
-
This is especially valuable during compliance reviews, fundraising, or enterprise sales processes.
