Bulletproof software, engineered to ship.
We think like attackers and build like architects. Web development, mobile apps, cyber security and penetration testing from New Delhi — fixed price, quoted in writing, shipped hardened.
Numbers we can show you.
Security buyers are paid to be sceptical. So this band carries only figures with a receipt behind them — a live site, a published page, or a clause in the contract you sign.
Security first.
The build follows.
Six services, one team, one contract. We break it, we harden it, and where you want us to, we build it too.
Penetration Testing
Manual, exploit-driven testing of web apps, APIs, mobile, cloud and networks. You get the exploit path and a fix order, not a scanner dump.
Cyber Security
Security audits, threat modelling, zero-trust architecture and compliance work — the engineering that stops the same finding coming back.
Ethical Hacking
Authorised adversary simulation under a signed scope: phishing, assumed breach, lateral movement and a report your defenders can act on.
Web Development
Fast, accessible React and Next.js sites and web apps — threat-modelled before the first commit and hardened before launch day.
App Development
Native and cross-platform iOS and Android apps, with secure storage, certificate pinning and auth that survives a real test.
Digital Marketing
SEO, Google and Meta ads, content and social — run for the products we build, and measured against leads rather than impressions.
The BytePatch offensive security methodology.
Ten phases, run in this order, on every engagement — whether it is a single API or a full adversary simulation. You get told which phase you are in while it is happening.
Scope
Assets, exclusions, test windows and the rules of engagement, signed by both sides before a single packet is sent.
Recon
Everything about you that is already public: subdomains, leaked credentials, exposed services, staff footprint.
Enumeration
Mapping the real attack surface — endpoints, parameters, roles, versions. Automated where it is honest, manual where it matters.
Threat modelling
What is actually worth stealing here, and who would want it. This decides where the manual hours get spent.
Manual testing
The part a scanner cannot do: business logic, authorisation between roles, workflow abuse, race conditions.
Exploitation
We prove the finding by exercising it, in scope, with evidence captured. No theoretical severities.
Privilege escalation
From the foothold: horizontal to another tenant, vertical to admin, lateral into the rest of the environment.
Impact assessment
What the chain actually costs you — records reachable, money movable, downtime, regulatory exposure.
Reporting
Executive summary, technical findings with CVSS and CWE, reproduction steps, and a remediation plan in fix order.
Retesting
Included, not billed. We re-run every finding against your fix and issue an attestation of what now holds.
Think you can't be hacked? Prove it.
Six short, playable simulations that drop you inside a real cyber-attack — from a different seat each time. Watch the hacker move, make the calls, and see exactly how companies get breached. Four are below; the rest are in the Range. Every run ends with a scored report and the fixes that would have changed the ending. No slides, no jargon.
Are You Hackable?
Run your company while a live hacker terminal reacts to every call you make.
Play →You've Been Hacked
It's 2 AM and the attacker is inside. Contain the breach before your data walks out.
Play →Ransom
Negotiate with a ransomware crew on a live dark-web portal. Pay, stall, or refuse.
Play →Red Team
Be the ethical hacker. Recon, break in, escalate, and own the network — legally.
Play →How exposed are you right now?
Ten questions about the ten things that actually decide whether an attacker gets in. Scored in your browser in about three minutes, with a written explanation of every point you lost and what to fix first.
No email required to see your score. Nothing is sent anywhere unless you ask us to look at it.
Six things we put in writing.
Not a promise page. Every line below is in the terms you sign, and you can read them before you talk to us.
A fixed price, before we start
Quoted in writing after a free discovery call. Scope changes are re-quoted in writing too — never billed as a surprise at the end.
Security included, not upsold
Hardened headers, secure auth, dependency scanning and an OWASP Top 10 review ship with every build. They are not a line item you discover later.
A free retest after we report
On every security engagement. A finding is not closed because we wrote it down — it is closed when we have checked the fix ourselves.
A reply within 24 hours
From a person who can answer the question, not a form acknowledgement. Monday to Saturday, 10:00 to 19:00 IST.
We will tell you not to hire us
If the scoping call shows you need something smaller, something else, or nothing at all, that is what the call concludes. It costs us a project and saves you one.
Your work stays yours
Confidential by default. Nothing appears in our portfolio, a case study or a talk without your written say-so.
We publish what we find.
Labs is the research half of BytePatch: papers, technical guides, the Cyber Range and the tools we build for our own engagements. Free, never locked behind a form you cannot skip, and written by the people doing the work.
The bench this site was built on.
No case study, no mock-up — this is the actual board behind bytepatch.tech. Open a track on the left, or type into the terminal below.
system?
Everything on the board is how bytepatch.tech is actually built — hand-written HTML, CSS and vanilla JavaScript, no database, no framework runtime. Want the same bench pointed at your product? Start a project.
Let's build something bulletproof.
Startups, SaaS, fintech, healthcare, enterprise — tell us which one you are and what you need tested or built. A person replies within 24 hours with a real answer, and the discovery call is free.
