Are you secure?
Many business websites have never had a security review. Here is what that can mean in practice, and what we commonly see.
Your customers' card details get stolen
Weak site security makes it easier for attackers to intercept payment and personal details entered on your site — and you're the one left liable for the fallout.
Your site gets locked and held to ransom
Attackers can lock up your systems and demand payment just to hand back access to your own website and data.
Your customers' details leak online
Names, emails, addresses and passwords get exposed. Depending on where your customers are, that can mean legal penalties on top of losing their trust.
Your own website gets turned against visitors
Attackers can quietly plant code on your site that redirects visitors to scam pages or steals what they type into your forms — without you ever knowing.
Your business goes offline
Out-of-date software is usually how attackers get in. Once they're in, they can take your whole site down — every sale, booking or enquiry stops until it's fixed.
Your insurance refuses to pay out
Most cyber-insurance policies require the basics to be in place. A breach caused by something this simple can mean a denied claim, leaving you to cover it yourself.
Most of this is automated. Scanners look around the clock for common gaps and act when they find one, so the practical goal is to cover the basics.

SharkCore applies the engineering discipline behind its own platforms to the security of client systems, including smart contracts and on-chain execution paths as well as ordinary servers and web applications.
We start with a free, passive check, then agree a written scope before any deeper testing.
Free website health check
Before any audit or engagement, we run a free, fully passive scan on your public site — the same kind of read your browser silently does every time it loads a page. No login attempts, no hidden folders, no probing for exploits. Just what's already publicly visible, reported back to you honestly.
Missing Security Headers
Checks for the protections a site can switch on against clickjacking, code injection and data leaks — settings many sites never enable.
Cookie Configuration
Confirms cookies are flagged Secure and HttpOnly, so they can't be intercepted or read by malicious scripts.
TLS / SSL Grade
Grades your encryption configuration against industry-standard benchmarks, flagging outdated or weak setups.
Exposed Software Versions
Flags server software versions visible in public headers — a signal that patching and maintenance may have lapsed.
None of this proves a site is vulnerable. These are signs of neglected basics, which is exactly what automated scanners look for.
How we secure our own systems
These are the practices behind the platforms we build and run ourselves.
Private by design
Internal services listen only on the machine itself, behind an encrypted front door, so nothing is exposed that does not need to be.
Strong sign-in
Signed sessions, hashed passwords, login rate limits and owner-only controls for sensitive actions.
Protected secrets
Keys and mailbox credentials are encrypted or held outside the database, and are never shown in the app.
Fenced fetching
Tools that read customers’ websites refuse to reach private network addresses.
Safe updates
Every change is tested, backed up and health-checked, and rolls back automatically if anything fails.
Under a defined engagement
We undertake this work under a written scope agreed in advance.
Smart Contract Review
Manual line-by-line review paired with automated static analysis.
Penetration Testing
Testing of web applications, APIs and server infrastructure, scoped to your actual attack surface.
Infrastructure Hardening
Server, network and deployment-pipeline reviews, closing the gap between “it works” and “it is defensible”.
Wallet and Key Security
Custody architecture reviews, multi-sig configuration and key-handling practices for teams managing real capital.
By arrangement
We also consider further work case by case, depending on the threat and your requirements: red team exercises, incident response, ongoing monitoring, on-chain threat intelligence, MEV and front-running defence, bug bounty management, secure pipeline reviews and social engineering assessments.
