Osto is the complete cybersecurity platform for startups. One platform that runs your full security stack, automates compliance directly from the security stack itself, delivers VAPT by OSCP-certified engineers, and answers security questionnaire in 5 minutes.
Most startups today end up paying for a compliance tool (Vanta, Drata, Sprinto), a separate stack of security tools that does not connect to it (WAF, endpoint protection, ZTNA, cloud posture management), an annual VAPT firm, and weeks of engineering time burned on security questionnaires.. An auditor who cannot tell the difference between configured and operational.
Osto replaces all of that.
CLOUD SECURITY
- Cloud Posture (CSPM): Scan AWS, Azure, GCP for misconfigs and drift
- Web API Protection: Shadow API discovery, schema enforcement, malicious traffic blocking
- Web App Protection: OWASP Top 10, DDoS, bot blocking, virtual patching
APPLICATION SECURITY
- Mobile App Scanner: Assess mobile app builds for weaknesses before release
- SAST / SBOM: Static analysis and software bill of materials
- Web App Scanner: Continuously scan internet-facing applications for exploitable issues
- SCA (Software Composition Analysis): Detect known vulnerabilities in open-source dependencies and third-party libraries used by your application
- License Compliance: Surface and track open-source licenses in your codebase to avoid legal and IP exposure
NETWORK SECURITY
- Domain Filtering: Block malicious domains, enforce browsing policies
- ZTNA Secure Access: Zero Trust with 2FA, time-based permissions, instant blocking
ENDPOINT SECURITY
- App Control: Control application behavior to reduce unauthorized execution risk
- Device Control: Control USB peripherals and removable media access on company devices
- Disk Encryption: Protect startup devices and sensitive data at rest
- Endpoint Antimalware: Real-time malware detection, ransomware prevention
- File Access DLP: Protect sensitive files with access controls and data-loss prevention
- Screen Lock: Enforce automatic device lock and idle-session protection
- Swipe Clean: Remote wipe and cleanup actions for managed startup devices
COMPLIANCE
- AI Security Q&A: Pre-fill questionnaires in 5 minutes at 99% precision
- Compliance Automation: Continuously mapped controls, evidence collection, and audit workflows (SOC 2, ISO 27001, HIPAA, PCI-DSS)
- Security Awareness Training: Train employees continuously and keep participation evidence audit-ready
AUDITS
- Logs Analyzer: Centralized logs and audit-ready posture across every module
ASSESSMENT
- VAPT: OSCP-certified engineers, 2 weeks+ delivery, covering web applications, APIs, networks, mobile, and source code
This is what we call TrulyOne: Osto's vision of one cybersecurity platform for startups, where everything you build, protect, and prove runs as a single system. Compliance evidence flows directly from the security stack, audit readiness becomes continuous rather than quarterly, and one dashboard replaces 5-7 separate vendors plus the annual VAPT firm plus manual GRC work.
Built for startup founders going from first enterprise deal to Series B and beyond, where compliance is no longer optional and the cost of fragmented security tools adds up fast.
