Real feedback from founders, CTOs, and security leaders who rely on us to secure their most critical systems and data.
Ned, Mel and his team are fantastic. Please hire them for all your future security needs.
Cyrus
CEO, BLS
Great team, very well coordinated, supported us on our timeline and budget. Highly recommend for startups and for those who need MVPs reviewed for clinical trials.
Dexter
Co-Founder, MiiHealth AI
Red Threat did an excellent job pen testing our application. We were very happy with their work and will hire them again.
Sean Harris
Founder, Kyva
Nadheera and Mel were thorough and clearly know their stuff. They identified issues I had not considered and left the site significantly more secure than when they started. Straightforward to work with, too. I would recommend.
Anna Saboisky
Founder, One of Twelve
Professional, detailed, and highly knowledgeable in HIPAA security and compliance. The deliverables were thorough, organized, and immediately useful.
Dr. Siddarth Saini
Founder, RadPro AI
They understood the healthcare context and gave us clear, practical security findings we could act on immediately.
Healthcare AI Founder
QuantCare
The team went beyond automated scanning and focused on the business logic issues that actually mattered to our product.
CTO
SaaS Platform
Their report was clear enough for leadership and technical enough for our developers. That balance made remediation much easier.
Founder
FinTech Company
RTCS understood the risks around AI workflows better than most vendors we spoke with. Their testing helped us identify weak points before launch.
Engineering Lead

RTCS AppSec Shield™
Application Security & Penetration Testing
Manual-first application security testing that thinks like an attacker. We uncover critical weaknesses across your attack surface before attackers do.
- Manual-First Testing
- Real Attacker Mindset
- Actionable Results
Attack Surface Reality
Your application is an attack surface.
Modern applications are complex, connected, and constantly changing. Attackers target weaknesses in code, logic, APIs, identity, and access - not just infrastructure.
Broken Access Control
Attackers exploit weak permissions to access sensitive data and restricted actions.
API Authorization Flaws
IDORs, excessive data exposure, and weak object-level controls.
Business Logic Abuse
Flaws in workflows, rules, payments, approvals, and user journeys.
Production Exposure
Misconfigurations, sensitive resources, debug paths, and exposed services.
Coverage Matrix
What RTCS AppSec Shield™ covers
Web Application Penetration Testing
Test complex web applications for OWASP Top 10 risks and deeper exploit paths.
API Security Testing
Validate REST, GraphQL, gRPC, and backend APIs for security weaknesses.
Authentication & Session Testing
Test login, session management, MFA, password reset, and token security.
Authorization & RBAC Testing
Assess role-based access controls, privilege boundaries, and tenant isolation.
Business Logic Testing
Identify logic flaws that attackers can abuse for real-world impact.
Cloud & Third-Party Integrations
Evaluate integrations, exposed storage, service trust, and cloud-connected risks.
Secure Code & Configuration Review
Review risky code paths, configurations, headers, secrets, and framework settings.
Compliance-Ready Reporting
Clear executive and technical reports aligned with major security standards.
Manual-First Validation
Not just a scan. A real attack simulation.
- 01 Recon Map the attack surface.
- 02 Auth Testing Break auth and session controls.
- 03 API Abuse Test APIs for excessive access.
- 04 Privilege Escalation Find paths to higher access.
- 05 Data Impact Assess sensitive data risk.
- 06 Remediation Prioritize and validate fixes.

Buyer Questions
Frequently asked questions
RTCS AppSec Shield is RTCS's application security and penetration testing service for web applications, APIs, SaaS platforms, and business-critical software.
Automated scanners support coverage, but AppSec Shield focuses on manual validation, authorization testing, business logic abuse, exploitability, and developer-ready remediation guidance.
Timeline depends on application size, number of user roles, APIs, and testing depth. A focused assessment can be scoped quickly after reviewing the application and business requirements.
Yes. AppSec Shield reports can be structured to support audit evidence, vendor security reviews, remediation tracking, and compliance readiness workflows.
Yes. Findings include practical remediation guidance, and RTCS can support developer discussions, remediation planning, and retesting.
Testing boundaries, timing, accounts, and restrictions are agreed during scoping. The objective is to validate risk safely while avoiding unnecessary production disruption.
