Verify, Defend,and Engineer the Next Era.

Systematic identification and risk prioritization of architectural, implementation, and configuration vulnerabilities across web applications, APIs, mobile apps, and cloud environments.

Web applications, REST / GraphQL / gRPC APIs, iOS and Android applications, and AWS / GCP cloud configurations (IAM policies, network boundaries, storage permissions).

Manual expert review combined with targeted tooling aligned with OWASP Web Security Testing Guide (WSTG), OWASP Application Security Verification Standard (ASVS), OWASP API Security Top 10, and CIS Benchmarks.

Comprehensive Vulnerability Assessment Report (executive summary, CVSS severity ratings, step-by-step reproduction evidence, and concrete code/configuration remediation examples) plus a post-remediation verification report.

Scenario-driven adversarial simulation evaluating whether chained vulnerabilities could allow an attacker to breach perimeter defenses, escalate privileges, move laterally, or reach high-value assets—while testing the effectiveness of detection and response controls.

Internet-facing perimeters (External Penetration Testing), internal corporate or production networks (Internal Penetration Testing), and cloud-native environments (IAM role chains, container clusters, service meshes).

Goal-oriented testing aligned with PTES (Penetration Testing Execution Standard), NIST SP 800-115, and the MITRE ATT&CK framework.

Penetration Testing Report detailing attack path narratives, defensive control and alerting evaluation, attack timeline, and prioritized architectural remediation roadmap.

Technical validation of newly disclosed CVEs or complex software defects to determine real-world exploitability within a client’s specific architecture, assess blast radius, and verify the efficacy of patches or compensating controls.

Software, middleware, custom modules, and staging environments owned by the client or explicitly authorized in writing for testing.

Reproduction and impact evaluation conducted strictly within JOS-managed isolated environments logically separated from client production networks, with outbound traffic restricted to an allow-list and logged (or within client-designated staging environments), followed by remediation verification to confirm that patches or WAF rules completely neutralize the exploit path.

Technical Verification Report including root-cause analysis, benign/defanged Proof-of-Concept (PoC) scripts for internal patch testing, impact assessment, temporary mitigation rules, and patch verification results.

Rapid technical investigation of suspicious binaries, scripts, and compromised hosts to determine malware capabilities, command-and-control (C2) behavior, and intrusion root causes, supporting containment and recovery.

Suspicious executables, scripts, document samples, memory dumps, and system/cloud audit logs from suspected security incidents.

Static and dynamic analysis performed inside JOS-managed isolated environments logically separated from client production networks, with outbound traffic restricted to an allow-list and logged (isolated sandboxes), extraction of Indicators of Compromise (IOCs), behavioral mapping against MITRE ATT&CK, and triage guidance aligned with NIST SP 800-61.

Malware Analysis Report (sample capabilities, persistence mechanisms, C2 protocol breakdown), actionable IOC packages (YARA rules, file hashes, network indicators), and containment/hardening recommendations.

Collection and analysis of emerging threat campaigns, vulnerability exploitation trends, and supply-chain risks tailored to your industry and technology stack to support proactive defense.

Enterprise CSIRT/SOC teams, engineering leadership, and executive decision-makers.

Multilingual OSINT (Open-Source Intelligence) covering English, Japanese, and Chinese-language sources, structured analysis of sector-specific threat trends, vulnerability intelligence triage, and executive briefings translating technical threat data into strategic risk decisions. All collection is strictly limited to lawful open sources and licensed feeds.

Tailored Threat Intelligence Reports, prioritized defensive action advisories, and executive-level threat briefings.

Specialized security assessment and architectural hardening for applications powered by Large Language Models (LLMs), Retrieval-Augmented Generation (RAG), and autonomous AI agents.

Customer-facing and internal LLM applications, RAG pipelines, agentic workflows with tool/API execution, and enterprise AI platforms.

Comprehensive testing aligned with the OWASP Top 10 for LLM Applications, evaluating direct and indirect prompt injection, sensitive data leakage (system prompt extraction, cross-tenant RAG leakage), privilege escalation and excessive agency via tool/function calling, and insecure output handling—combined with AI governance and guardrail design support.

AI Security Assessment Report (test cases, transcript evidence, severity ratings, input/output guardrail architectures, and RAG permission-boundary designs) and Enterprise AI Security Guidelines.

Embedding threat modeling, zero-trust access boundaries, cryptographic key management, and observability directly into the blueprint of new and modernized systems.

New web and SaaS platforms, enterprise system modernizations, cloud migrations, and high-reliability production infrastructure.

STRIDE threat modeling, OWASP ASVS, NIST SP 800-207 (Zero Trust Architecture), KMS envelope encryption, OpenTelemetry immutable audit logging, and automated CI/CD security guardrails (SAST, SCA, IaC scanning).

Data Flow Diagrams (DFDs) and Threat Models, Architecture Decision Records (ADRs) for authentication and authorization boundaries, hardened Terraform IaC modules, and incident response runbooks.
