End-to-end Vulnerability Assessment and Penetration Testing delivered as a managed service—covering discovery, exploitation, reporting, and remediation guidance without burdening your internal team.
In-depth penetration testing of web applications targeting OWASP Top 10 vulnerabilities, including SQL injection, XSS, authentication bypass, and business logic flaws.
Rigorous assessment of REST and GraphQL APIs to detect authentication weaknesses, excessive data exposure, broken access controls, and abuse scenarios that standard scanners miss.
Simulated attacks against servers, firewalls, cloud environments, and network segments to expose misconfigurations, privilege escalation paths, and lateral movement opportunities.
Targeted security assessments across AWS, Azure, and GCP environments identifying IAM misconfigurations, exposed storage, insecure serverless functions, and cloud-native attack vectors.
Machine learning-powered automated scanning that categorizes vulnerabilities by severity, pinpoints affected endpoints, and delivers step-by-step remediation guidance with 2x faster execution.
We work closely with your team to define the exact targets, testing boundaries, timelines, and acceptable risk levels—ensuring a thorough, controlled engagement that aligns with your compliance requirements and business continuity needs.

Experts dedicated to simplifying cybersecurity for modern, growing businesses.
Osto was built on a singular conviction: that growing businesses, startups, and scaling enterprises deserve enterprise-grade cybersecurity without the complexity or cost of building large internal security teams. Since its founding, Osto has rapidly evolved from core web application protection into a comprehensive, AI-powered cybersecurity platform. The team has delivered multi-cloud security posture management across Azure, AWS, and GCP, advanced web application and API protection, Zero Trust Network Access, and AI-driven vulnerability detection—all within a unified, easy-to-use platform. Guided by the principle of 'One Stop Cybersecurity for New Age Businesses,' Osto's security specialists combine deep technical expertise with a commitment to clear communication, ensuring clients not only understand their risks but have the precise tools and guidance to eliminate them.
Penetration testing services involve authorized security professionals simulating real-world cyberattacks against your systems, applications, or infrastructure to identify exploitable vulnerabilities. Unlike automated scanning alone, pen testing validates whether vulnerabilities are genuinely exploitable, demonstrates potential business impact, and provides a prioritized remediation roadmap—giving you evidence-based insight into your actual security posture.
