Red Sentry vs UnderDefense

About Red Sentry

Red Sentry sells offensive security services, from one-off penetration tests to ongoing PTaaS (Penetration Testing as a Service) partnerships. Red Sentry supports web application, API, network, cloud, compliance-focused, and PTaaS engagements. Red Sentry combines tooling with human-led testing to uncover business logic, chained vulnerabilities, and real-world exploit paths. The core penetration testing from Red Sentry covers web, network, and cloud assets to meet SOC 2 and ISO standards. For mature security teams, Red Sentry offers advanced Red Teaming and adversary simulation.^[1][3][5][6]

Red Sentry assesses iOS and Android apps for flaws such as insecure data handling, API abuse, and authentication bypasses. In web application penetration testing, Red Sentry attempts to view other users' data (IDOR) or escalate privileges to Admin status by manipulating requests. Red Sentry source code review pairs tool-assisted static analysis with manual security review and validation. Red Sentry offers source code review as a standalone service. Red Sentry may support additional languages, including Solidity, Scala, and Perl, in source code reviews, depending on scope, technology, and reviewer availability.^[5][7]

For infrastructure, Red Sentry tests public-facing IPs and services without credentials in external network testing. Red Sentry simulates threats originating from stolen credentials, insider threats, or compromised devices. In cloud testing, Red Sentry combines configuration review with active exploitation. Red Sentry physical security assessment tests whether physical controls, people, and processes prevent unauthorized access to agreed locations and objectives. Red Sentry offers the physical security assessment as a standalone service.^[8][9]

Red Sentry describes a Red Team Operation as a simulated full-scale attack that tests an organization's people, processes, and technology. Red Sentry follows the MITRE ATT&CK framework to simulate the entire lifecycle of a breach. Red Sentry red teams collaborate with the Blue Team to explain exactly how controls were bypassed. Red Sentry social engineering campaigns measure a team's security awareness by simulating the tactics used by ransomware gangs and APT groups. Red Sentry runs phone-based attacks to test staff handling of sensitive info. Red Sentry social engineering reporting includes a breakdown of who opened, who clicked, and who submitted data.^[10][11]

Red Sentry delivers its work through a PTaaS platform. PTaaS means penetration testing as a service, and it gives teams a central place to track findings, remediation, retesting, communication, and report delivery. Every Red Sentry engagement includes full access to the PTaaS platform at no extra cost. Red Sentry portal access lets teams track project status, access reports and evidence, communicate with the project team, and manage remediation. Red Sentry reports include clear reproduction steps, often with video or screenshots. Red Sentry manually validates reported findings and demonstrates exploitability where appropriate.^{[1][3][5][6][12]}

Red Sentry includes one round of remediation testing for source code review findings when requested within 90 days of report delivery. Red Sentry makes one round of remediation testing available for API testing findings when requested within 90 days of report delivery. In network testing, Red Sentry verifies fixes and does not charge extra to double-check its work. Red Sentry physical assessments do not include remediation testing by default.^{[2][6][7][9][13]}

On compliance, Red Sentry maps every finding directly to the audit framework of the client. Red Sentry helps organizations work out which assessments their SOC 2 environment needs, then runs them by hand from scoping to final report. Red Sentry reports include an executive summary, full technical findings mapped to Trust Services Criteria, reproducible steps, prioritized remediation guidance, a Letter of Attestation when applicable, and one complimentary retest. Red Sentry locks scope and pricing before testing starts. Red Sentry offers specialized testing to secure Cardholder Data Environments (CDE). Red Sentry provides technical testing and supporting evidence, and the client's auditor determines compliance.^{[1][6][9][12][14]}

Red Sentry has completed a SOC 2 Type II examination conducted by an independent CPA firm. Red Sentry testers hold certifications such as OSCP, CISSP, CREST, and CCSP.^{[3][5][6][7][9][10][11][12][14]}
