What You’ll Get From Our Cyber Security as a Service

A zero-hassle route to high-level cyber security

Cyber security is a complex landscape of software, services and jargon. Expecting your overwhelmed IT team to handle this critical duty can be unrealistic. Work with Intersys to get high-level coverage that delivers peace of mind and frees up your IT team’s time to do what they do best.

24/7 monitoring from AI and security experts

Our cyber security as a service provides experienced live engineers and AI 24/7 monitoring, detection and response, to pinpoint and neutralise threats quickly. Sophisticated security information and event management (SIEM) tools recognise threats and vulnerabilities before they can wreak havoc.

A cost-effective alternative to in-house security

Our cloud-based subscription model reduces upfront costs and provides predictable expenditure. Retaining your own IT security team (average salary £51,415 according to Glassdoor) and implementing software and infrastructure is expensive. With Intersys, you’ll get better for less..

Compliance for highly regulated industries

Does your current cyber security provider have a thorough understanding of EU Annex 11 in relation to pharmaceuticals? Or UK-GDPR for the financial services industry? Intersys understand the requirements of highly regulated sectors – to ensure you are 100% compliant.

Fast route to maturity & scalability

With Intersys’ cyber security as a service, you’ll benefit from the latest technology, rapidly implemented by experienced engineers. This lowers risk and provides the assurance you are meeting the regulatory requirements of your sector from the word go.

Educating Your People:
a Crucial Part of Managed Security Operations

One of your best defences against cyber criminals is a security-conscious workforce. As a part of our cyber security as a service, our Cyber Security Training Programme raises your employees’ awareness, so they help to keep criminals out.

Our programme provides:

  • Cyber security risk assessments, to quantify the profile of and threat to your user base.
  • Tailored security awareness content, including interactive modules, games, and simulated phishing campaigns.
  • Dedicated ‘phish alert’ buttons to raise awareness of threats.
  • A Virtual Risk Officer to provide feedback and insight into your employees’ cyber-risk.
  • Monthly reports providing insights into the effectiveness of your security plan and actionable next steps.

Meet Some of our Cyber Security Clients

Intersys provide comprehensive Cyber Security as a Service (CSaaS) to dozens of clients in over 25 different sectors in areas as diverse as life sciences, pharmaceuticals, the media, mining and engineering, education, renewables and financial services.
We also work with many partners in highly regulated industries. This means we understand and follow crucial digital compliance mandatories from The FCA, the EU and other governing bodies. Ask us about DORA, EU Annex 11 or GDPR rules and we will guide you towards 100% compliance.
Biotech start-up: protecting IP and business data
Horticultural business: cyber security training

Housing Association: enterprise-level firewall

CSaaS for Highly Regulated Industries: A Case Study

A start-up biotech company wanted to focus on creating innovative new medical therapies – not spend its time protecting against property theft and compliance, or setting up a complicated in-house SOC.

Our ISO 27001-certified team built a full-scale managed security operations solution that exactly mirrored expected industry standards and met all GDPR compliance rules.

They innovate, we protect.

Our Cyber Security as a Service in Detail

Every client has unique needs, so this is not an exhaustive list. But it describes our core CSaaS offer and some of the additional value we can bring to you.

A comprehensive security plan
Sourcing the right cyber and IP assurance, system monitoring and intrusion protection to defend your organisation.
Security information and event management (SIEM)
Our service includes sophisticated SIEM (security information and event management) AI tools. We will collect, analyse and correlate data from various sources across your IT infrastructure, providing real-time monitoring, threat detection, incident response and compliance reporting capabilities. This provides high-level monitoring of activity across your network so we can respond quickly to threats and ensure your compliance.
Microsoft 365 monitoring
Including proactively monitoring and enhancing your Secure Score, and actively responding to alerts.
Cloud access monitoring
Deploying internal network monitoring and user activity monitoring, so you know exactly who is accessing your systems.
External penetration testing
Stress testing your systems and ensuring they are robust enough to repel attacks.
Swift breach response
A rapid-response service should a successful breach occur, with urgent on-site assistance.
Compliance expertise
Helping to ensure your cyber security strategy is GDPR and industry compliant.
Perimeter monitoring
Next-generation firewalls send alerts when: viruses are intercepted; there is an network intrusion attempt; and even when sensitive information gets sent outside the organisation.
Anti-virus monitoring
We manage your antivirus of choice or install our recommended solution. Alerts are directed to the SOC desk and issues identified and dealt with before they can spread.
Email filtering
Best-in-class email filtering will block email malware, spam and phishing emails.
Threat detection and incident response with SIEM
We use the latest cyber security AI such as Microsoft Sentinel to help us spot, investigate and deal with security risks before they can actually do any damage.
Annual security hardening roadmap
At the start of our engagement, an Intersys strategic consultant will work with your IT team to identify areas in need of hardening and put together a plan to strengthen your network and protect your data.
Office 365 backup
Intersys works with Acronis to provide best-in-class backup from Microsoft 365 to ensure that your emails and files stored in the cloud are safe from any errors or accidental deletion.
Zero trust / application whitelisting and ringfencing
We will lock down your computers to ensure that only pre-approved applications can run. This means it is almost impossible for a virus or ransomware to run on one of these machines.
Privilege Access Management (PAM)
Additional administrative permissions can be a weak link in your company’s IT security. However, some software or job roles require this to function properly. PAM allows administrative access on request, so users can work effectively without compromising your network.
Cyber Essentials Certification
We will work with your team to help you achieve Cyber Essentials Certification. We manage the process and assist with the steps needed to become compliant.
Endpoint sensor / compliance monitor
We install specialised software on each computer that scans the device software, checks the version and identifies any vulnerabilities or sensitive information such as passwords and credit card details. Intersys staff will identify the most at-risk computers and work with your team to rectify any issues found.
Automated PEN testing
We set up automatic vulnerability scans for your network perimeters and OWASP scans for your website to look for vulnerabilities. Our team will review the findings with you and advise on steps to remediate any issues found.
Dark web monitor
Our dark web service scans hacker forums and databases looking for references to your users’ information. As soon as information about your organisation is found on the dark web, we will work with your team to ensure the accounts are secured and no longer at risk.
Security specialist consultancy
Our security specialists can undertake hardening projects for your network, either working with your IT team or managing the project themselves.
Secure web gateway
Get granular control over your devices wherever they are in the world. We provide unified control over all network traffic using web and DNS filtering, so traffic on all machines is reviewed before it hits the endpoint.
Online cyber security training
Your staff will have access to a customised training portal with over 50 cyber security training modules they can complete at their leisure. You can even assign different courses to your specialist staff, to ensure they have the relevant training. Each course consists of a short video followed by a multiple-choice quiz.
Email attack simulation
To ensure your staff can spot suspicious emails, our team will simulate phishing attacks. We can monitor staff that have clicked on these bogus links and entered in credentials. This approach can be integrated with cyber security training to ensure staff vulnerable to attacks receive extra attention – and ALL of your staff can spot a malicious email.
Regular security meetings
Our SOC specialists will meet with your staff on a regular basis (monthly for Gold packages and fortnightly for Titanium) to review SOC alerts, identify trends or weak points in the network, and advise on steps to make your network more secure.
