What Red Sentry does
Red Sentry is an offensive security company providing human-led penetration testing and vulnerability management services, founded in 2020 and headquartered in Atlanta, Georgia. The company's core offering is a platform-plus-services model centered on its proprietary PTaaS (Penetration Testing as a Service) platform, which delivers real-time visibility into vulnerabilities as they are discovered by testers, project management timelines aligned to audit observation windows, and audit-ready reports mapped to SOC 2, HIPAA, PCI DSS, ISO 27001, NIST, and FDA/IEC frameworks. Service breadth spans web application, API, network (internal/external), cloud (AWS/Azure/GCP), mobile, social engineering (phishing/vishing/smishing), red team operations using MITRE ATT&CK, and specialized offerings including medical device pentesting, blockchain/smart contract testing, and LLM/AI assessments. Technical execution is led by senior US-based testers holding OSCP, OSEP, and CREST certifications, with 85 industry certifications across the team and a stated focus on human verification to eliminate false positives produced by automated scanners.
The PTaaS platform is bundled with every engagement and integrates natively with Jira and Slack, supports role-based access control for separating developer and auditor views, and provides remediation tracking with complimentary retests. Red Sentry operates a sales-led GTM with three pricing tiers: One-Off Testing starting at $4,200, Professional subscriptions at $25,000+ minimum (150 hours), and custom Enterprise engagements (650+ hours minimum). A channel partner program extends reach through MSPs, IT companies, and compliance platforms, with Vanta and Secureframe serving as core referral partners. Customers span healthcare, government, FinTech, SaaS, legal, education, biotech, manufacturing, and energy verticals, with a stated base of 1,000+ companies and 1,000+ security assessments conducted.
Red Sentry is privately held with no disclosed funding rounds, no parent company, and no public ownership structure, suggesting it is founder-led and likely bootstrapped or profitable. Leadership consists of co-founder Valentina Flores (CEO) and co-founder Alex Thomas (CTO). The company has achieved SOC 2 Type II certification for its own operations and has earned 2026 Global InfoSec Awards, Software Advice Best Customer Support 2026, and Capterra Best Ease of Use 2026 recognition. Strong review-platform presence (4.8/5 on G2, Capterra, GetApp, and Software Advice) supports brand credibility, while multiple strategic partnerships and an expanding vertical and product surface point to an active growth posture.

Products and services
- PTaaS (Penetration Testing as a Service) Platform A centralized cloud-based command center for managing offensive security engagements. Provides real-time vulnerability visibility, project timelines, dedicated project manager communications, and audit-ready reporting. Includes native Jira and Slack integrations and is included at no extra cost with every Red Sentry engagement.
- Penetration Testing Human-led authorized cyberattack simulations covering web applications, APIs, mobile apps, networks (external and internal), and cloud environments. Performed by OSCP/OSEP/CREST-certified ethical hackers who manually exploit vulnerabilities to demonstrate real-world business risk.
- Red Teaming Full-scope, objective-based attack simulations that test people, processes, and technology simultaneously. Uses MITRE ATT&CK framework to simulate the entire breach lifecycle, including initial access, lateral movement, and privilege escalation, to achieve defined objectives such as data exfiltration.
- Social Engineering Human-element security testing covering phishing (email), vishing (voice), and smishing (SMS) campaigns. Includes custom scenario development, click-rate analysis, just-in-time training redirects, and trend tracking to measure security awareness improvement over time.
- Web Application Penetration Testing Manual testing of web applications for OWASP Top 10 flaws such as SQL injection, XSS, and broken access control, plus business logic vulnerabilities, authentication and session management weaknesses, and API security (REST, GraphQL).
- Network Penetration Testing External and internal network security assessments. External tests public-facing infrastructure for misconfigurations; internal simulates insider threats to evaluate lateral movement, segmentation, and Active Directory security. Includes complimentary retesting after remediation.
- Cloud Security Penetration Testing Security testing for AWS, Azure, and Google Cloud environments. Identifies IAM misconfigurations, publicly exposed storage, insecure storage buckets, and policy weaknesses, and tests whether compromised instances can lead to account takeover.
- Medical Device Penetration Testing FDA-compliant penetration testing for medical device manufacturers. Covers premarket and postmarket cybersecurity per FDA guidance, IEC 62304, ISO 13485, IEC 60601, HIPAA, and EU MDR, including SBOM analysis and post-market surveillance support.
