Cybersecurity competencies
Reduce security risk and stay ready as your business grows
Sunbytes brings together security assessment, technical testing, compliance readiness and ongoing security expertise to help businesses understand their exposure, address priority risks and maintain stronger security over time.
Cybersecurity takes more than a one-off test
A security test shows what is vulnerable at one point in time. It does not by itself show whether findings are fixed, controls remain effective, or evidence is available when customers, auditors, or internal stakeholders ask for it.
Sunbytes combines technical security, governance, compliance, and remediation into a single security context. Our ISO/IEC 27001-certified Information Security Management System provides a defined governance framework for managing information security risks.
That means security can move beyond identifying issues to understanding exposure, validating risk, strengthening controls, verifying remediation, and maintaining the evidence behind them.
Cybersecurity expertise across the security environment
Security risk rarely sits in one place.
Sunbytes brings together technical, operational and governance capabilities to examine how systems are built, exposed, controlled and maintained.
-
Security posture & risk
Build a clearer view of security risk across systems, processes and controls, identifying gaps and areas that need closer attention.
This creates a practical baseline for deciding where testing, remediation, governance or compliance work should focus next.
-
Application & product security
Examine how security is implemented across applications and digital products, including access, code, data handling and exposed functionality.
Findings can then be connected to the engineering changes needed to strengthen the product.
-
Infrastructure & exposure
Assess infrastructure, cloud environments and exposed systems for vulnerabilities, configuration gaps and potential attack paths.
The focus is on understanding where exposure exists and where hardening or deeper investigation should be prioritized.
-
Security governance
& controlsReview how security responsibilities, access, reviews and controls are managed across the organization.
The goal is to keep ownership and control activities clear, repeatable and demonstrable as systems and teams change.
-
Compliance
& evidenceMap existing controls, documentation and evidence against the requirements the organization needs to address.
This helps identify readiness gaps and structure the work required for audits, customer reviews or compliance programmes.
-
Remediation
& assuranceTurn findings into prioritized corrective actions and support the path from remediation through verification.
Retesting and supporting evidence provide a clearer record of what has been addressed and what still requires attention.
Capabilities across the security lifecycle
Sunbytes supports security from the first assessment through remediation and ongoing control, bringing in the right capability at each stage.
-
1. Understand exposure
Establish the context, assets, controls and security questions that need to be examined.
-
2. Validate risk
Use assessment and technical testing to determine whether suspected weaknesses are real and how significant they are.
-
3. Prioritize action
Rank findings using technical severity, exposure and business context so remediation effort goes to the right places first.
-
4. Remediate
Translate findings into corrective actions with clear technical context and ownership.
-
5. Verify & maintain
Retest where required, document closure and keep controls and evidence current as the environment changes.
Technical security capabilities
Sunbytes applies different testing approaches depending on what needs to be examined, from broad vulnerability exposure to deeper application, code and adversarial testing.
-
Penetration Testing
Test applications, systems or infrastructure against defined attack scenarios to identify exploitable weaknesses and understand their practical security impact.
Findings are prioritized with technical context and remediation guidance so teams can focus first on the issues that create the most meaningful risk.
-
Vulnerability Scanning
Identify known vulnerabilities and exposed weaknesses across relevant systems or infrastructure through structured scanning.
Scanning can support an initial security view or recurring monitoring, helping teams track exposure and determine where deeper investigation is required.
-
Secure Code Review
Review source code for security weaknesses that may not be visible through external testing alone, particularly around application logic and implementation.
The review gives development teams clearer technical findings and remediation guidance that can be addressed closer to the code itself.
-
Adversary Assessment
Examine how systems, controls, and teams respond to more realistic attacker behavior rather than testing isolated vulnerabilities alone.
The assessment can expose weaknesses across multiple layers and provide a broader view of how existing security measures perform when challenged together.
Security expertise for different needs
Different security needs require different starting points. Sunbytes brings the right expertise to establish a security baseline, prepare for compliance requirements or maintain ongoing security ownership as the business evolves.
CyberCheck
Establish a baseline of the current security posture, identify relevant gaps and determine which risks need attention first.
Compliance Readiness
Assess controls, documentation and evidence against the relevant requirements and structure the work needed before an audit or certification process.
CyberCare
Maintain ongoing security ownership, follow-up and review as systems, controls and requirements continue to change.
Evidence, not just recommendations
The output should help the responsible team understand what was found, what needs to change and what proves that the issue has been addressed.
A clear baseline
A structured view of the environment, relevant controls and the security gaps that require attention.Prioritized findings
Findings organized around severity, exposure and practical impact rather than an undifferentiated list of issues.A remediation path
Specific corrective actions, ownership and follow-up requirements that give technical and business teams a clear route forward.Verified evidence
Retest results, reports and supporting records that demonstrate what was fixed and what remains open.

behind our cybersecurity work
Customer success is our priority
A pentest that went beyond the surface
A new authentication layer needed deeper validation. Sunbytes combined manual and automated grey-box testing to uncover and classify vulnerabilities, then guided the team through the findings and remediation options.
Grey-box pentest · SOC 2 & ISO-aligned reporting · 9 findings classified
From concept to a working prototype in 3 sprints
SandGrain needed to turn its post-quantum authentication concept into a secure, scalable cloud platform without compromising reliability. Sunbytes assembled a seven-person multidisciplinary team and delivered a functional prototype in three sprints.
15 releases · 3,380 test cases · 1,777 automated tests
Six weeks from security testing to launch readiness
Methodemeter was preparing to launch a digital education platform without dedicated in-house security expertise. Sunbytes ran a black-box pentest, guided remediation, and aligned testing with GDPR, NIS2 and ISO 27001.
6-week test-to-fix cycle · GDPR, NIS2, ISO 27001 · Launched clean
Web, API and mobile tested before an IPO security audit
C2C needed its production product tested across web, API, iOS and Android before an IPO security audit. Sunbytes ranked each finding and provided remediation guidance the team could act on.
Web, API, iOS & Android · All identified findings remediated · 5.0 Clutch review
