Cybersecurity built in,
not bolted on
after the breach.
We build secure software from day one, authentication, data protection, secure coding practices, compliance, and secure API design. We've shipped healthcare platforms, financial systems, and research databases where security wasn't optional. It still isn't.

The security worries that bring teams to us
If one of these is keeping you up, here is what we do about it.
You shipped fast and now you are not sure what is exposed.
A structured security review. We threat-model the app, test against the OWASP Top 10, and hand you a prioritised findings report with fixes, not a 200-page scan dump.
A customer or investor is asking for a security questionnaire you cannot answer.
We close the gaps and document them. Auth hardening, encryption in transit and at rest, audit logging, and access control mapped to what the questionnaire actually asks.
You handle health or payment data and "GDPR-compliant" is currently a hope.
Compliance designed into the architecture. Data residency, retention, and access control built against your obligations. We built Rezi24, a GDPR-compliant German healthcare SaaS on German data centres.
Security keeps getting bolted on at the end of each project, then breaking.
Secure development practices baked in. Parameterised queries, encoded output, and role-based access as defaults in every sprint, reviewed before code reaches staging.
What we cover
Security isn't a checkbox at the end of the project. We build it into the architecture, the code patterns, the deployment, and the monitoring.
Secure architecture & design
Threat modelling from day one. Data classification, trust boundaries, least-privilege design, secrets management (Vault, AWS Secrets Manager). Security baked into the architecture decisions before a line of code is written.
Authentication & access control
JWT with proper rotation, OAuth2/OIDC, MFA, RBAC with field-level permissions, session management, account lockout. We've built auth for healthcare platforms with strict access requirements, we know what "secure" actually means here.
Vulnerability & hardening review
We review against the OWASP Top 10, auth bypass, injection, broken access control , using automated scanning tools and manual review of our own code, then fix what we find. For a formal, certified penetration test, we'll point you to a dedicated pen-test firm.
Data protection & encryption
Encryption at rest and in transit. PII handling and data minimisation. We build to the data-handling guidelines a client's compliance programme requires. Secure backups. Column-level encryption for sensitive fields , not just database-level.
Security code review
We review existing codebases for security vulnerabilities, injection risks, insecure deserialization, broken auth, missing input validation, exposed secrets. Good for teams who've shipped fast and need to know what they've accumulated.
Compliance & audit trails
Technical controls built to the client's own compliance requirements, access control, encryption, immutable audit logs for all write operations. Data retention policies, right-to-erasure workflows, consent management. We build the technical controls auditors check for, the audit itself, and any certification, is handled by your compliance team or a certified auditor. We don't certify compliance ourselves.
Who this is for
Good fit
- SaaS founders handling user data, payments, or healthcare records
- Products that have shipped fast and need a security review
- Companies with client-directed data-handling requirements (GDPR, HIPAA)
- Teams who need secure development practices baked in, not audited after the fact
Probably not you
- You want a basic marketing site, basic SSL and headers are enough
- You need an active incident response team (we're developers, not a SOC)
- Offensive red-team operations for public infrastructure, not our scope
- You're looking for the cheapest possible review, meaningful security work takes real time
We secure the AI features other teams are shipping without thinking about it
Every LLM feature adds attack surface: prompt injection, data leakage through the model, over-permissioned agents. Our engineers build AI to production, so we know where it breaks. It is how our own products, Tully AI and Mebag, were built.
Input handling, output filtering, and tool-call scoping so a crafted message cannot hijack the model.
What reaches the API, what the model can retrieve, and where PII needs filtering or anonymising first.
Least-privilege tokens and human-in-the-loop checkpoints so an autonomous step cannot do real damage.

How a security engagement works
Whether we're building secure from scratch or reviewing what you have.
Scope & threat modelling
We start by understanding what you're protecting: what data, what users, what regulatory context, what attack surfaces. A threat model before any code review or testing.
Architecture review
For existing systems: we review your architecture, data flows, and auth model. For new builds: we design the security architecture before development starts. Missing controls get flagged here, not in production.
Code review & vulnerability scanning
Static analysis, manual code review, and automated vulnerability scanning. We check for what a real attacker would try, auth bypass, injection, broken access control, API enumeration, not just running a scanner and calling it done.
Remediation
We don't just hand over a report, we fix the issues. Remediation is included in our engagements. We patch, re-test, and verify the fixes before closing the finding.
Hardening & monitoring setup
CSP headers, rate limiting, WAF configuration, audit logging, alerting on suspicious patterns. Security doesn't end at launch, we set up the monitoring so you know if something changes.
Retest & sign-off
Once fixes are in, we retest every finding and give you a clear closing report: what was found, what was fixed, and what residual risk you are accepting. Annual retests and pre-release reviews are available on a retainer.

Pricing
Security work is priced by scope, what you're protecting, how large the codebase is, and how deep you need us to go. We quote a fixed price after that scoping call, never an hourly rate.
Codebase review against the OWASP Top 10, auth review, dependency audit. Full findings report with remediation steps. For products preparing for a client security review or going into regulated industries.
- Full code security audit
- OWASP Top 10 vulnerability review
- Dependency vulnerability scan
- Report + remediation roadmap
- 3–5 week engagement
Security built into a new product from scratch, architecture, auth design, data protection, audit trails, vulnerability review before launch. Compliance-ready on day one.
- Threat modelling + architecture
- Secure auth implementation
- Data encryption + audit logs
- Pre-launch vulnerability review
- Compliance documentation
- 8–16 week engagement
OWASP Top 10 secure-coding practices and encryption built through the whole system, access control, data protection, audit logging, to the data-handling guidelines your client or industry requires. For teams heading into enterprise sales who need the technical foundations in place. We don't run certification audits, that's a certified third-party auditor's job, not ours.
- OWASP Top 10 practices sitewide
- Encryption at rest and in transit
- Access control & audit logging
- Data-handling documentation
- Ongoing security programme
All engagements start with a free scoping call. We'll size the engagement honestly.

Common questions
Straight answers on testing vs development, reports, remediation, timelines, and cost.
Are you a penetration testing firm or a development agency?
Development agency that does security. We're not a pure-play pen test firm , we build secure software for a living and can test what we build and what others have built. For a pure red-team engagement, you'd want a dedicated security firm. For building things securely from the start, that's us.
Do you issue formal penetration test reports?
No, we're not a certified pen-test firm, so we don't issue reports suitable for enterprise procurement sign-off. What we do provide: a vulnerability and hardening review of the code we build, with findings, remediation, and a re-test after fixes. If you need a certified pen-test report, we'll point you to a dedicated firm and work alongside them on remediation.
Can you help us prepare for SOC 2 or ISO 27001?
Yes, for the technical build-out. We do gap analysis against the control requirements, implement the technical controls (logging, access management, encryption, incident response), and produce documentation auditors expect. We work alongside your compliance team or vCISO, we handle the technical implementation, a certified auditor handles the actual certification.
We've shipped fast and never had a security review. Where do we start?
A security code review and vulnerability scan. That gives you a current-state picture: what's actually vulnerable vs. what's fine. Most teams find a handful of real issues and a lot of "good enough", the review tells you which is which. Takes 3–5 weeks; cost depends on codebase size, which we scope on the call.
What compliance standards do you work with?
GDPR, HIPAA, and the OWASP Application Security Verification Standard (ASVS) inform how we build. We also implement the technical controls SOC 2 requires, alongside your auditor. We've worked with clients in healthcare, fintech, legal, and education, all different compliance landscapes. We'll map your specific requirements at the start of the engagement.
Do you offer ongoing security retainers?
Yes. Monthly retainers cover: quarterly dependency audits, monthly log reviews, security-aware code review on pull requests, and access to us for security questions as your product evolves. Good for teams who've gone through a one-off engagement and want to stay on top of it.
353 reviews. 5.0 average.
Platform-level reviews of the agency — not cherry-picked project comments.
What I love about Team7 is that they always say: No worries, we can find a solution. This is the mindset of builders, creators, people who do not have fear, the partner you need if you want to excel.
Working with Mo and his team over the past year has been nothing short of exceptional. I was admittedly sceptical about investing such a large amount, but results exceeded every expectation.
Their responsiveness and willingness to take on our challenging task were impressive.
