Penetration testing services for business-critical systems

Penetration Testing & Red Team

Web application penetration testing

Test customer-facing and internal applications for risks such as OWASP Top 10 vulnerabilities, broken business logic, access control gaps, injection flaws, and authentication issues before attackers can exploit them.

Penetration Testing & Red Team

API penetration testing

Evaluate REST, GraphQL, internal, external, and authorized third-party APIs for risks such as broken authorization, insecure endpoints, data exposure, weak authentication, and resource consumption or rate-limit gaps that can affect customers or operations.

Penetration Testing & Red Team

Network penetration testing

Find exploitable weaknesses across internal and external networks. Validate exposed services, segmentation gaps, weak protocols, misconfigurations, and privilege escalation paths.

Penetration Testing & Red Team

Mobile app penetration testing

Test iOS and Android applications for insecure storage, weak authentication, API abuse, and platform-specific security gaps. Identify reverse engineering and tampering risks where applicable.

Penetration Testing & Red Team

Cloud and infrastructure testing

Review authorized cloud workloads, identity controls, storage exposure, network rules, and infrastructure configurations. Strengthen access permissions, environment hardening, and attack-path visibility before risk reaches production.

Penetration Testing & Red Team

Red team assessment

Simulate realistic attack paths to test whether your people, processes, and security controls can prevent, detect, and respond to threats.

Penetration Testing & Red Team

Ethical hacking services

Use controlled exploitation to validate vulnerabilities and show business impact. This helps uncover exploitable weaknesses that automated tools often miss.

Penetration Testing & Red Team

Penetration testing as a service (PTaaS)

Run recurring or on-demand testing as your applications, APIs, and environments change. Keep security testing aligned with product releases and business growth.

Penetration Testing & Red Team

Social engineering testing

Assess human-layer risk through phishing, impersonation, and pretexting simulations. Use the results to improve awareness and response readiness.

Find security gaps before they impact revenue

tkxel helps scaling businesses test real attack paths, prioritize exploitable risks and give engineering teams clear remediation guidance before audits, security reviews or incidents.

How tkxel turns security testing into clear remediation

01

01 Define scope and objectives

Set clear testing goals, target systems, access levels, timelines, exclusions, business priorities, and compliance requirements so the engagement stays focused and useful for your team.

Deliverables: Scoping document, rules of engagement, target asset list, testing access plan, compliance requirements summary

02 Gather intelligence and map the environment

Collect technical details, enumerate assets, analyze architecture, and identify exposed attack surfaces to understand how an attacker could approach approved systems.

Deliverables: Reconnaissance summary, attack surface map, asset inventory, exposed services list, environment overview

03 Run automated scanning and static/dynamic testing

Use automated tools, DAST, dependency checks, configuration reviews, and, where access is available, SAST outputs to detect known flaws across applications, APIs, infrastructure, and cloud components.

Deliverables: Automated scan results, static and dynamic testing findings, dependency issue summary, configuration review findings, initial vulnerability list

04 Perform manual testing and exploitation

Apply expert penetration testing and ethical hacking techniques within the agreed scope to validate exploitability, test business logic, chain vulnerabilities, and uncover deeper risks that automated tools may miss.

Deliverables: Manual testing findings, exploitation evidence, proof-of-concept details, business logic findings, validated vulnerability list

05 Analyze risks and prioritize findings

Assess severity, exploitability, business impact, affected assets, customer exposure, compliance relevance, and remediation urgency so teams know what to fix first.

Deliverables: Risk-ranked findings, severity matrix, business impact summary, prioritized remediation plan, compliance impact notes

06 Document results and guide remediation

Provide a structured report with vulnerability details, evidence, affected assets, technical recommendations, and practical guidance for engineering, security, and leadership teams.

Deliverables: Executive report, technical penetration testing report, remediation guidance, affected asset summary, developer-level recommendations

07 Retest and validate fixes

Conduct targeted retesting to confirm resolved vulnerabilities, validate remediation, and verify that critical risks have been addressed.

Deliverables: Retest validation report, fix verification summary, updated vulnerability status, closure evidence, residual risk notes

What our penetration testing delivers for growing businesses

Validated exploitable risk

Understand which vulnerabilities can actually be exploited, not just which issues appear in automated scan results.

Stronger application, API, and cloud security

Identify weaknesses across web apps, APIs, mobile apps, networks, cloud systems, and infrastructure before attackers abuse them.

Clearer remediation priorities

Get severity, business impact, technical evidence, and prioritized fixes so lean engineering teams know what to address first.

Support for audits and customer reviews

Use structured reporting to support PCI, SOC 2, ISO 27001, HIPAA, vendor reviews, and customer security requirements.

Verified risk reduction

Validate remediation through retesting so leadership and technical teams have evidence that critical fixes were completed.
