Penetration Testing That Finds the Gaps Before an Attacker Does
Cyber security consultancy helps you find and close weaknesses in your systems before a real attacker finds them. We run penetration tests and vulnerability scans within a scope agreed in writing, review web applications and factory networks (IoT/OT), rank the findings by risk and give a practical fix for each one.
Attackers rarely pick targets by company size; they look for an open door. An unpatched server, a camera left on its default password or an admin panel exposed to the internet is enough for a data leak, a ransomware incident or a halted production line.
This service is for organisations that want to know how well their systems would actually hold up. We test your infrastructure under controlled conditions, rank the findings by risk and write a practical fix for each one. Because we build our own IoT devices and industrial software, we also understand operational technology such as factory networks, PLCs and SCADA, not just office IT.
Cyber Security Consultancy Services
Penetration Testing
Controlled attack attempts against web applications, APIs, network infrastructure and wireless networks, within a scope agreed in writing. Scenarios draw on the OWASP Top 10 and published CVEs.
Vulnerability Scanning
Servers, network equipment and IoT devices are scanned for known flaws, ranked by CVSS score, with guidance on which patches to apply first and their likely impact.
IoT & OT Security Reviews
We examine the attack surface of smart devices, PLCs, SCADA systems and industrial networks: outdated firmware, unencrypted protocols and the separation between office and production networks.
Web Application Security
Checks for SQL injection, XSS, CSRF, weak authentication and misconfiguration, with optional source-code and security architecture review.
KVKK / GDPR Technical Measures
Access control, encryption and logging are reviewed on the systems that hold personal data. For a full compliance programme, see data protection compliance.
Awareness Training
Phishing simulations, real social-engineering examples and a clear incident-reporting procedure, plus technical security training for the IT team.
How an Assessment Runs
01
Scope & Authorisation
Target systems, testing windows and limits are set out in writing, and a confidentiality and authorisation agreement is signed.
02
Discovery & Scanning
Systems visible from outside and inside, open ports and known vulnerabilities are identified.
03
Validation
We confirm whether findings can really be exploited, under controlled conditions and without disrupting service.
04
Report & Remediation Plan
Findings are reported in order of severity, each with a fix and a priority. A retest after remediation is available on request.
The Same Rules Apply to What We Build
Our own software and IoT systems follow secure development practice: parameterised queries, OWASP-based checks and secure authentication are standard. For example, Smart360 uses human verification on its sign-in screens and stores mailbox passwords encrypted with AES-256-GCM, while SmartMail assesses every incoming email against 12 signals, including SPF, DKIM and DMARC.

Frequently Asked Questions
What is a penetration test?
A penetration test is an authorised, controlled attack on your systems from an attacker's point of view. The scope, time window and limits are agreed in writing beforehand. Web applications, APIs, network infrastructure and wireless networks are tested with scenarios based on the OWASP Top 10 and known CVEs, so weaknesses are found before a real attacker finds them.
What is the difference between a penetration test and a vulnerability scan?
A vulnerability scan looks for known weaknesses on servers, network devices and IoT devices and ranks them by CVSS score. A penetration test goes further and verifies, under controlled conditions and without disrupting service, whether those weaknesses can actually be exploited. Together they produce a prioritised fix list showing which patch to apply first.
How does a security assessment run?
In four steps: the systems and limits are agreed in writing and a confidentiality and authorisation agreement is signed; externally and internally visible systems, open ports and known vulnerabilities are identified; exploitability is verified in a controlled way; and findings are reported by severity, each with a fix and priority.
Do you test factory networks, PLCs and SCADA systems?
Yes. An IoT and OT security review examines the attack surface of smart devices, PLCs, SCADA systems and industrial networks: outdated firmware, unencrypted protocols and the separation between office and production networks. Because Digital Bridge builds its own IoT devices and industrial software, we understand operational technology, not just office IT.
Do you provide security awareness training?
Yes. Awareness training covers phishing simulations, social engineering examples and the incident reporting procedure, with separate technical security training for IT teams. A device left on its default password or one clicked fake link can undo technical safeguards, so the people side is part of every assessment.
