Overview
Security built in — not bolted on after a breach.
The average cost of a data breach reached $4.45 million in 2025. 28% of exploits land within 24 hours of a CVE disclosure — before most organisations even know a patch exists. Security is not an optional layer you add before a compliance audit. It is an engineering discipline built into every commit, every deployment, and every API endpoint.
We provide the full range of offensive and defensive cybersecurity services: penetration testing that proves exploitability rather than listing theoretical risks, VAPT covering web applications, APIs, mobile apps, and cloud infrastructure, application security integrated into the SDLC, and compliance readiness for SOC 2, GDPR, HIPAA, PCI DSS, and ISO 27001.
We sit at the intersection of software development and security — which means our findings come with developer-ready remediation code, not just a list of CVE identifiers. A vulnerability found by us is a vulnerability fixed in your codebase, not a report filed in a ticketing system.

Most In-Demand · 2026
Penetration Testing
A controlled attack on your systems by a security expert attempting to exploit vulnerabilities — proving whether a risk is theoretical or actually exploitable. A scanner tells you a SQL injection pattern exists; a penetration tester shows you the extracted database records. We run black-box, grey-box, and white-box tests on web apps, APIs, mobile apps, and cloud — with CVSS-scored findings, proof-of-concept exploit detail, and developer-ready remediation.

Systematic Coverage
VAPT — Vulnerability Assessment & Pen Testing
VAPT combines vulnerability assessment (systematic scanning to identify all weaknesses) with penetration testing (attempting to exploit confirmed vulnerabilities). Assessment alone produces long CVE lists prioritised only by CVSS. Combined, each finding is validated as exploitable, false positives are eliminated, and priority is based on actual business risk. We combine CVSS base scores with EPSS data and asset criticality — less than 1% of CVEs are ever weaponised, making CVSS-only dangerous.
Automated scanningManual validationCVSS + EPSS scoringRisk-based priorityAsset criticality

Application Security & DevSecOps
AppSec integrates security testing into the development process rather than running assessments after code ships. We implement SAST with Snyk or SonarQube on every commit, DAST against running staging environments, SCA for vulnerable dependencies, secrets scanning, and container scanning with Trivy. The result is security feedback in the IDE and PR review, not a quarterly external report. A vulnerability found in code review takes 15 minutes to fix; one found in production takes days and a postmortem.

Enterprise Requirement
Compliance Readiness
SOC 2, GDPR, HIPAA, PCI DSS, and ISO 27001 define specific security controls you must implement and evidence before an audit. We run gap analysis against the relevant framework, identify missing controls, implement technical controls (encryption, access logging, MFA, segmentation), and produce the audit evidence package. Non-compliance costs 2.65× more than compliance once fines are accounted for — cumulative GDPR fines alone exceed €5 billion.

9 cybersecurity services we deliver.
Every offensive and defensive security capability — from code to cloud.
Web application penetration testing
OWASP Top 10 coverage, authentication bypass, session management, SQL and NoSQL injection, XSS, CSRF, and business logic flaws — with manual testing that goes beyond automated scanner output.
API security testing
OWASP API Security Top 10 — BOLA/IDOR, broken authentication, excessive data exposure, rate-limiting bypass, and mass assignment. REST, GraphQL, and gRPC tested with authenticated and unauthenticated sessions.
Mobile application security testing
iOS and Android testing covering insecure data storage, certificate-pinning bypass, traffic interception, insecure deep links, and hardcoded secrets in binaries. OWASP Mobile Top 10 aligned.
Cloud security assessment
AWS, GCP, and Azure configuration review — IAM over-privilege, exposed S3 buckets, security-group misconfigurations, unencrypted storage, public databases, and exposed secrets in environment variables.
Compliance gap analysis
SOC 2, GDPR, HIPAA, PCI DSS, or ISO 27001 gap analysis — mapping current controls against framework requirements and producing a prioritised remediation roadmap with effort estimates for each gap.
SAST & DAST integration
Static and dynamic testing integrated into your CI/CD pipeline — SAST on every commit, DAST against staging on every deployment, with PR feedback and severity-gated quality gates that block critical vulnerabilities from merging.
Threat modelling
STRIDE threat modelling applied to your architecture — identifying attack vectors, trust boundaries, and data flows before features are built rather than after vulnerabilities are found.
Security awareness & developer training
Developer-focused training covering the OWASP Top 10, secure coding patterns in your stack, secrets management, dependency tracking, and incident-response basics — tailored to your languages and frameworks.
Incident response planning
Incident-response playbooks, tabletop exercises that simulate a breach, escalation procedures, breach-notification obligations under GDPR and CCPA, and recovery runbooks — so your team has a plan before the 3am alert fires.
OWASP Top 10 — the 10 risks we test for.
OWASP Top 10 is the global standard for web application security risk. Every penetration test we run covers all 10.
A01
Broken Access Control
CriticalUsers access data or functions outside their authorised scope — reading other users’ records, modifying another account, or reaching admin functions as a regular user. The most critical OWASP risk.
A02
Cryptographic Failures
CriticalSensitive data transmitted or stored without adequate encryption — passwords in plaintext, card numbers unmasked in logs, or TLS configured below 1.2. Previously "Sensitive Data Exposure."
A03
Injection
CriticalUntrusted data sent to an interpreter — SQL injection extracts records, OS command injection executes server commands, LDAP injection manipulates queries. SQL injection CVSS scores regularly reach 9.0+.
A04
Insecure Design
HighSecurity flaws in architecture rather than implementation — business logic vulnerabilities, missing rate limits enabling brute force, workflows allowing unintended state transitions. Requires threat modelling.
A05
Security Misconfiguration
HighDefault credentials, open cloud storage, verbose errors with stack traces, unnecessary features enabled, missing security headers (CSP, HSTS, X-Frame-Options). The most frequently found finding in manual testing.
A06
Vulnerable & Outdated Components
HighLibraries and dependencies with known CVEs — Log4Shell (CVSS 10.0) is the canonical example, turning every application using log4j into an actively exploited target within hours of disclosure.
A07
Authentication & Identification Failures
HighWeak passwords permitted, no MFA on admin accounts, JWT tokens with algorithm:none accepted, session tokens not invalidated on logout, or credential-stuffing attacks not rate-limited.
A08
Software & Data Integrity Failures
HighCode or data used without integrity verification — CI/CD pipeline compromise, insecure deserialisation, auto-updates that don’t validate signatures. Includes supply-chain attacks on npm, PyPI, or GitHub Actions.
A09
Security Logging & Monitoring Failures
MediumInsufficient logging means attacks proceed undetected for an average of 204 days. Missing audit logs also fail SOC 2, PCI DSS, and HIPAA requirements that mandate logging of authentication and data access.
A10
Server-Side Request Forgery (SSRF)
HighThe application fetches a user-supplied URL, letting attackers reach internal services — cloud metadata endpoints (169.254.169.254), internal databases, or Kubernetes API servers — not reachable from the internet.
6 compliance frameworks we prepare you for.
Enterprise customers check for compliance before signing. We get you there before they ask.
SOC 2 Type II
Covers 5 Trust Service Criteria — security, availability, processing integrity, confidentiality, and privacy. Type II spans a 6–12 month observation period; enterprise deals above $50,000/year require it. We implement the 64 AICPA controls and produce the auditor’s evidence package.
GDPR
Requires data-subject rights (erasure, access), privacy by design, breach notification within 72 hours, and DPIAs for high-risk processing. Fines reach 4% of annual global turnover or €20M — whichever is higher. Cumulative GDPR fines exceeded €5 billion in 2025.
PCI DSS
PCI DSS v4.0 applies to any system that stores, processes, or transmits cardholder data — 12 requirements covering network security, data protection, vulnerability management, access control, and monitoring. Quarterly ASV scans and annual penetration tests are mandatory.
HIPAA
The Security Rule requires technical safeguards for ePHI — access controls, audit logs, transmission security, and workstation security. A Business Associate Agreement is required with every vendor touching PHI. Civil penalties reach up to $1.9 million annually per violation category.
ISO 27001
The international standard for an Information Security Management System — 93 controls across organisational, people, physical, and technological themes. Unlike SOC 2, ISO 27001 certification is recognised globally and preferred by EU and APAC enterprise customers.
NIST Cybersecurity Framework
NIST CSF 2.0 (2024) provides 6 functions — Govern, Identify, Protect, Detect, Respond, Recover. The US government standard, widely adopted as a baseline; NIST 800-53 and 800-61 add control sets. Not a certification, but increasingly required in enterprise vendor questionnaires.

Why Work With Hoop
Security findings that get fixed, not filed.
Most penetration test reports list CVE identifiers and CVSS scores. We deliver findings with the exact remediation code for your stack — so a critical SQL injection is fixed in a pull request within hours, not a ticket that sits for 3 months.
- 01
Developer-first security reports
Reports written for the engineers who fix issues, not just the CISO who reads them. Each finding includes the vulnerable code snippet, the attack scenario, a CVSS score with rationale, and a concrete remediation in your tech stack — not generic "sanitise inputs" advice.
- 02
CVSS + EPSS combined prioritisation
We don’t prioritise solely by CVSS score. Less than 1% of CVEs are ever weaponised. We combine CVSS base score, EPSS probability, your asset criticality, and current threat intelligence to surface the 5% of findings that deserve immediate action.
- 03
Retest included in every engagement
After you remediate, we retest every critical and high vulnerability to confirm the fix is complete. A penetration test without a retest only confirms what was broken — it doesn’t confirm the repair works.
- 04
Security built alongside development
We’re a software development firm with security capability — not a security firm that reviews other people’s code. Recommendations come with knowledge of your architecture, so advice is practical and implementation is fast.

What is penetration testing and how is it different from a vulnerability scan?
Penetration testing is a controlled attempt to exploit confirmed vulnerabilities in a system to demonstrate real-world business impact; a vulnerability scan is an automated tool that identifies potential weaknesses without attempting to exploit them. A scanner running against a web application flags 200 issues in 15 minutes. A penetration tester manually confirms which 12 are actually exploitable, chains findings together to reach a database, and provides screenshots of extracted records as proof. The distinction matters because organisations acting on unvalidated scan output waste resources fixing low-risk findings while missing exploitable flaws categorised as medium severity.
Penetration testing runs in five phases: reconnaissance, scanning, exploitation, post-exploitation (demonstrating lateral movement, data extraction, privilege escalation), and reporting. Black-box testing uses no prior knowledge of the target; grey-box uses partial knowledge such as user credentials; white-box uses full source-code access. The average cost of a data breach ($4.45 million) typically exceeds the cost of penetration testing by 100–200×.
What is the OWASP Top 10 and why does it matter?
The OWASP Top 10 is a consensus-based list of the 10 most critical web application security risks, updated every 3–4 years by the global security community based on real-world breach data. It standardises risk language between developers, security teams, and auditors — and OWASP Top 10 coverage is required by PCI DSS, referenced in GDPR technical control recommendations, and expected in most enterprise security questionnaires.
The 2021 list places Broken Access Control at A01 — where users access data outside their authorised scope. IDOR, where changing an ID parameter in a URL reveals another user’s data, is the most common Broken Access Control vulnerability in modern APIs. Injection (A03) remains the highest-severity individual class, with CVSS scores regularly reaching 9.0–10.0 for exploitable SQL injection. Security Misconfiguration (A05) is the most frequently found issue in manual testing — default credentials, verbose errors exposing stack traces, and missing HTTP security headers.
What is CVSS scoring and how should organisations prioritise CVEs?
CVSS scores vulnerabilities from 0.0 to 10.0 across three metric groups — Base (inherent characteristics), Temporal (exploit availability and remediation status), and Environmental (impact on your specific organisation). Critical is 9.0–10.0, High 7.0–8.9, Medium 4.0–6.9, Low 0.1–3.9.
CVSS-only prioritisation is insufficient in practice. Less than 1% of published CVEs are ever weaponised, so prioritising every Critical finding equally produces a list too long to act on. Effective prioritisation combines four factors: CVSS base score, EPSS probability (a model predicting exploitation likelihood within 30 days — a CVE with CVSS 8.0 but EPSS 0.1% is less urgent than one with CVSS 6.5 but EPSS 12%), asset criticality (a flaw in your authentication service outranks one in an internal analytics tool), and active threat intelligence. This surfaces the 1–2% of vulnerabilities that genuinely demand immediate attention.
What is the difference between SOC 2 and ISO 27001?
SOC 2 is a US-specific audit framework covering five Trust Service Criteria; ISO 27001 is an international certification standard covering 93 controls across four themes — and each wins different markets.
SOC 2 is the predominant requirement in the US enterprise SaaS market. Type I verifies controls are designed correctly at a point in time; Type II verifies they operated effectively over a 6–12 month period and is what enterprise customers actually require. SOC 2 is an attestation report issued by an independent CPA firm, not a certification.
ISO 27001 is a globally recognised certification preferred in EU, UK, APAC, and Middle East markets. It defines an ISMS with 93 controls and is a formal certification issued by an accredited body after a multi-stage audit. Companies selling across geographies increasingly pursue both — SOC 2 for US customers, ISO 27001 for international ones. Both require penetration-testing evidence as part of their controls.
What is Zero Trust architecture and how is it implemented?
Zero Trust is a security model that requires all users, devices, and services to be continuously authenticated and authorised before accessing any resource — eliminating the assumption that anything inside a network perimeter is trusted. The core principle is “never trust, always verify.”
Implementation spans five pillars. Identity verification: every request is authenticated — MFA for all users, machine identities via certificates, service-to-service calls via mTLS. Least privilege: only the minimum permissions required, not broad network or admin access. Micro-segmentation: networks split into small zones so a compromised service can’t reach unrelated systems — via Kubernetes network policies and cloud security groups. Continuous monitoring: all access, authentications, and API calls logged and analysed for anomalies in real time. Device health verification: access granted only from devices meeting posture requirements (patch level, EDR present, disk encryption). Zero Trust is a multi-year architecture programme, not a product purchase.

FAQ
Cybersecurity Questions
The things teams ask us most before every security engagement — answered directly.
Black-box testing uses no prior knowledge of the target and simulates an external attacker; grey-box uses partial knowledge such as user credentials or architecture diagrams; white-box uses complete access including source code. Black-box tests the external attack surface — finding what an unknown attacker discovers. Grey-box is the most common and cost-effective for web apps, testing authenticated and unauthenticated paths. White-box is the most thorough, finding vulnerabilities in business logic and code that only appear on code review — required by some compliance frameworks. We recommend grey-box as the default for most SaaS and web applications, with white-box for applications handling financial or health data.
A focused web application or API penetration test takes 3–5 business days for active testing, plus 2–3 days for report writing and 1 day for retest. Total engagement time is typically 2–3 weeks from scope agreement to remediation certificate. Mobile app tests take 3–4 days. Cloud security assessments take 2–3 days. Larger scopes — multiple applications, APIs, and cloud environments — scale proportionally. We scope testing time precisely after reviewing your architecture, so you know the duration and cost before starting.
No — not with proper scoping and a competent testing team. Professional penetration testing uses controlled exploitation techniques that demonstrate vulnerability without causing service disruption. Denial-of-service attacks are explicitly excluded from scope in our rules of engagement. We test against a staging or pre-production environment wherever possible. If production testing is required, we conduct testing during low-traffic windows and define specific out-of-scope systems that are never touched. An emergency contact and abort procedure is agreed before testing starts.
You need SOC 2 primarily for US enterprise customers; ISO 27001 for EU, UK, APAC, and international markets. SOC 2 Type II is required by most US enterprise procurement teams for vendor contracts above $50,000/year. ISO 27001 certification is globally recognised and preferred in regulated industries and government procurement outside the US. Both require penetration testing evidence as a control. Pursuing SOC 2 first makes sense if your primary market is the US; pursue ISO 27001 if you are targeting EU markets or regulated industries internationally. Increasingly, enterprise SaaS companies pursue both in sequence — SOC 2 first (6–12 months), then ISO 27001 (12–18 months).
SAST (Static Application Security Testing) analyses source code without executing it; DAST (Dynamic Application Security Testing) tests a running application from the outside. SAST finds vulnerabilities in code before the application is deployed — SQL injection patterns, hardcoded secrets, insecure function use, and dependency vulnerabilities — running in the CI/CD pipeline on every commit. DAST sends HTTP requests to a running application and analyses responses, finding runtime vulnerabilities like authentication flaws and session management issues that only appear when the application is live. Both are necessary: SAST alone misses runtime vulnerabilities; DAST alone misses code-level flaws in untested paths. We integrate both into CI/CD pipelines as part of DevSecOps engagements.
IDOR (Insecure Direct Object Reference) is an access control vulnerability where changing an ID parameter in an API request reveals or modifies data belonging to another user. For example, a user requests GET /api/orders/12345 and sees their order, then changes the ID to GET /api/orders/12346 and sees another user’s order. IDOR is common in APIs because developers often implement authentication correctly (you must be logged in) but miss authorisation (you must only access your own data). It appears under OWASP API Security as BOLA (Broken Object Level Authorisation) — the #1 API security risk. IDOR cannot be found by automated scanners because it requires understanding object ownership relationships; manual penetration testing is required.
A focused web application or API penetration test starts at $3,000–$8,000 USD; a comprehensive web app, API, and cloud assessment ranges from $8,000–$25,000 USD. Cost depends on scope (number of endpoints, applications, and cloud environments), test type (black vs grey vs white box), and whether compliance reporting is required. We scope precisely based on your architecture and provide a fixed-price quote — not hourly billing that creates uncertainty. The average data breach costs $4.45 million; penetration testing at a fraction of that figure to prevent it is straightforward ROI. We provide phased scoping so you can start with a high-priority scope and expand over subsequent engagements.
Yes. Security directly affects AEO (Answer Engine Optimisation) and GEO (Generative Engine Optimisation) because AI engines like ChatGPT, Perplexity, and Google AI Overviews prefer to cite content from secure, trustworthy sources — HTTPS enforced, no mixed-content warnings, and sites with a verifiable security posture. Beyond page security, structured cybersecurity content — direct answers to security questions with specific numeric values, named entities, and bold answers — is exactly the content format AI engines extract for citations. We structure educational content to be citable by AI answer engines and apply the same principles to any site we build or audit.
