Contact 04 — Security
We help small businesses protect themselves with practical, comprehensive IT security. Our services include advanced threat protection, regular security assessments and data encryption to safeguard your sensitive information.
We conduct thorough vulnerability scanning and penetration testing to identify and address potential weaknesses in your system. Using Microsoft Secure Score, we steadily improve your security posture and help you meet your compliance obligations.
Proactive measures and monitoring protect your business from cyber threats, so you can operate with confidence.
04.1 — Context
IT security is vital for small businesses as they face growing threats like data breaches, ransomware, and phishing attacks that can disrupt operations, lead to financial loss, and damage their reputation.
Without the in-house resources of larger organisations, small businesses must prioritise cybersecurity to protect customer data and comply with regulations such as UK GDPR.
iTransact offers security tailored to a small business’s needs and budget. With experience protecting against a wide range of cyber threats, we help small businesses strengthen their defences, maintain business continuity and keep their customers’ trust.
04.2 — Services
Vulnerability scanning identifies security weaknesses in your systems before they can be exploited. Regular scans help protect sensitive data, maintain customer trust and demonstrate compliance with regulations, reducing the risk of fines. They also show where security spending will do the most good.
Learn morePenetration testing simulates real-world cyberattacks to uncover vulnerabilities, so that security flaws can be fixed before they are exploited. It helps safeguard sensitive data and customer trust, supports compliance with industry requirements, and gives you clear priorities for improving your overall security.

Learn more04.3 — Vulnerability scanning
Identify vulnerabilities in systems, networks, and applications.
Assess risk and provide remediation recommendations.
Include network (perimeter & internal), applications, cloud environments, endpoints, mobile devices, and physical security devices.
Use tools such as Nmap, Nessus, OWASP ZAP and Amazon Inspector for network, web, endpoint and cloud scans.
Maintain an updated asset inventory.
Define risk baselines, schedule scans for low-traffic times and back up critical data.
Perform authenticated and unauthenticated scans, categorising vulnerabilities by severity.
Analyse and validate findings, then rate vulnerabilities by criticality.
Work with your on-site support team to apply patches, update configurations, implement security controls and train staff.
After remediation, rescan to verify fixes and set up continuous monitoring.
Create technical reports and executive summaries for stakeholders.
Schedule regular scans, update scope as needed, and monitor emerging threats.
Align scans with relevant legal and industry requirements (e.g. UK GDPR, PCI DSS).
This framework gives small businesses regular, thorough vulnerability management.
04.4 — Pen testing
Simulate real-world attacks to identify security weaknesses.
Assess the business's ability to detect and respond to attacks.
Define in-scope assets: network, systems, applications, cloud, and physical security.
Focus on high-risk areas like web applications, databases, and employee endpoints.
External testing: target public-facing systems (e.g. websites, firewalls).
Internal testing: simulate an attacker with internal access (e.g. a compromised employee account).
Social engineering: test staff awareness through simulated phishing and similar techniques.
Use tools such as Metasploit, Burp Suite, Wireshark and Nmap to perform attacks and scans.
Manually test for vulnerabilities where necessary.
Reconnaissance: gather information about the target (e.g. IP addresses, open ports).
Exploitation: attempt to exploit identified vulnerabilities.
Privilege escalation: try to gain higher-level access within systems.
Post-exploitation: assess what sensitive data or systems can be accessed.
Provide a detailed report of vulnerabilities, exploited weaknesses, and recommended fixes.
Offer an executive summary for non-technical stakeholders.
Work with the business to implement fixes.
Conduct a retest to ensure vulnerabilities have been addressed.
Align the test with any industry-specific security requirements (e.g. PCI DSS, ISO 27001).
This framework gives a small business a clear, efficient process for finding and fixing security weaknesses.
