Redcentric Solutions Limited

DDOS Mitigation Service

Distributed Denial of Service (DDoS) attacks are characterised by the delivery of very large volumes of traffic to the targeted system, overwhelming infrastructure and making it inaccessible. The DDoS Mitigation Service addresses this by filtering out attack traffic while sending as much legitimate traffic to the Customer’s systems as possible.


  • Mitigation is enabled on demand
  • An always on service is available
  • Traffic "scrubbing" removes attack traffic whilst forwarding legitimate traffic
  • "Scrubbing" occurs at upstream Tier 1 Internet transit suppliers
  • Baselines "normal" traffic established to better distinguish legitimate traffic flows


  • DDoS Mitigation forms part of an overall Business Continuity plan
  • Extremely large "scrubbing" capability
  • Baseline establishment of "normal" traffic allows legitimate traffic passed scrubbing
  • Prevents total blackout of customer services

Onboarding and offboarding

Getting started
Our project and delivery teams implement the service. In conjunction with the customer, our project, delivery and support teams will work with the customer to agree a window where a period of baseline network activity is carried out to populate the scrubbing service with “normal” traffic patterns. This involves turning on the service prior to any DDoS event. Information on DDoS event notification by the customer to our support desk is shared and general communications protocols for any attack notifications are established, as a number of DDoS attacks are pre-empted by the bad actor to the end customer.

Information security policies and processes
As a managed service provider that the delivers services into different vertical sectors (central government, NHS, legal, finance, manufacturing and so on), we take several measures to secure these assets. This requires work to implement, manage and be audited against a number of recognised security standards and frameworks. This benefits all our customers and also provides a recognised and repeatable methodology for delivering services to a higher security level, where required, for specific customer environments.
Redcentric’s policy is to deploy individual customers using physical and logical segmentation appropriate to the client’s operational requirements. Segmentation techniques and technologies including MPLS IP-VPN security, firewalls and VLAN technology are used to ensure a high level of security. Testing is typically done at a service provider level so as to not impact specific customer deployments.
It is the responsibility of Redcentric to provide an assured managed service infrastructure to deploy client services over. Whilst some aspects of security can be abdicated to the client’s service provider Redcentric recommend that customers perform their own assurance testing within the context of their business setting and context. Redcentric will always co-operate with customers around any testing activities and subsequent outcomes.

Operational security

Configuration and change management standard
Supplier-defined controls
Configuration and change management approach
Redcentric maintains an ISO 27001 audited configuration and change management process for customer hosting infrastructure. Initial customer hosting deployments are initially configured by a combination of automated provisioning tools and expert system administrators. Newly deployed infrastructure is subject to a peer review prior to being put live.
Customer change management is performed according to Redcentric internal ticketing processes and workflows, providing customers with the ability to request and plan changes by Redcentric system administrators, authorisation mechanisms and visibility of work performed on their hosting environment.
Vulnerability management type
Conforms to a recognised standard, for example CSA CCM v3.0 or SSAE-16 / ISAE 3402
Vulnerability management approach
Redcentric proactively manages vulnerabilities within the corporate infrastructure and all infrastructure connected to or participating within 3rd party external networks such as the healthcare network, the public internet and other corporate or partner networks or customer hosting domains.
Redcentric conducts quarterly or as required automated in-depth vulnerability scans of critical internal infrastructure including administrative and orchestration systems, underlying customer host servers, backup infrastructure, edge and intermediate firewalls and load balancers using Nessus. These scans are automatically parsed by our internal configuration and change management system and items requiring investigation escalated directly to DevOps.
Protective monitoring type
Conforms to a recognised standard, for example CSA CCM v3.0 or SSAE-16 / ISAE 3402
Protective monitoring approach
Redcentric can provides a range of protective monitoring services including vulnerability management and auditing and assessment services
(such as SIEM).
Redcentric will work with the customer to put in place an approach to Proactive Monitoring which meets the requirements of the customer.
Incident management type
Conforms to a recognised standard, for example, CSA CCM v3.0 or ISO/IEC 27035:2011 or SSAE-16 / ISAE 3402
Incident management approach
Redcentric maintains a formal incident management process for internal and customer-impacting incidents that includes triage, containment and remediation and root cause analysis. Roles are defined to provide responsibility for overall command, communications and technical authority. Workflows and related information are managed by our centralised internal ticketing system. Redcentric will inform customers of any security incident that directly impacts on their hosting solution in a timely manner once detected.
Redcentric defines a customer impacting security incident as a security-related problem which may have actively impacted on the confidentiality, integrity or availability of more than one customer.

Energy efficiency

Energy-efficient datacentres
Description of energy efficient datacentres
We have a number of existing facilities which were built before 2011 in use today which have been reviewed and modified to increase their ‘Energy Saving Levels’. No new facilities have been built since this time.
When new IT equipment or software is sourced and deployed, we review how we can increase our ‘Energy Saving Levels’ and factor this into designs.
As well as being an operator of services from our facilities we also provide co-location and private cloud hosting. Under the EU code of conduct we endeavour whenever upgrading our facilities to review increasing our ‘Energy Saving Levels’. Where a customer is procuring their own IT equipment, we offer advice and guidance.
In adhering with the EU Code of Conduct for Energy Efficient Datacentres we are committed to;
• The fulfilment of relevant compliance obligations
• Continually working towards improving the environmental management system to enhance environmental performance
• Protection of the environment, including the prevention of pollution and sustainable use of resources
• Working towards incorporating environmental factors into business decisions as standards.

Social Value

Fighting climate change

Fighting climate change

In recent times ESG has become an important subject for consideration by the boards of companies across the globe and there is increasing demand for transparency and accountability in this area. The UK government has committed to a Net Zero Strategy, with a target to achieve nationwide Net Zero by 2050 and plans to introduce mandatory Sustainability Disclosures Requirements in line with the Taskforce for Climate-related Financial Disclosures framework.

Redcentric is fully supportive of this approach, and it is in the process of developing its reporting capabilities in this area. We are committed to developing an ESG strategy that aligns with UN Sustainable Development Goals, to updating our ESG scoring, keeping abreast of the regulatory environment, conducting materiality assessments, publishing our strategy and updating our website with key corporate policies. We are also committed to developing a long-term strategy to achieve Net Zero. Currently Redcentric’s power requirements are met 100% by green energy sources.

We are looking to engage with a consultancy firm who will help us to develop a net zero strategy and with some of our ESG reporting requirements that sit under the Environmental pillar. The Board of directors of the Company (the “Board”) is cognisant of the growing importance of ESG and is currently developing a comprehensive corporate ESG strategy with targets to drive further accountability across the business. A full ESG plan will be published at the time of the Company’s preliminary results announcement.

We have maintained our ISO 14001:2015 certification for three years.
Redcentric is a company listed on AIM (Alternative Investment Market), we are required to publish our carbon emissions in our annual reports which are published on the Redcentric website.

Our Environmental Management System (EMS) was introduced 2018. It is a documented system which is reviewed regularly.
Covid-19 recovery

Covid-19 recovery

As a key partner to the NHS and working with our healthcare customers, we delivered solutions that enabled business continuity during the pandemic through the provision of secure remote access solutions, national infrastructure, and collaboration services. Redcentric is also proud to have played an active role in supporting the NHS throughout the pandemic, providing services which have provided vital connectivity for new Nightingale hospitals and vaccination hubs.

As we move forward from the pandemic, we continue to support our NHS, wider public sector organisations and commercial customers as they move to the new way of working. Providing hosting for critical national infrastructure and solutions that deliver secure access regardless of location and collaboration tools supporting disparate teams.

The covid-19 pandemic and the resulting impact had a material influence over the trading environment in which we have operated. Initially we dealt with a surge in demand at the outbreak of the pandemic however we also dealt with a reduction in large scale IT projects as people waited for market and wider environment to stabilise.

At Redcentric we continued to operate following our business continuity plan with all staff having the ability to work remotely and only those with roles that dictated it on site, the business did not need to furlough at any point.

We have seen encouraging signs of increased customer interactions again and the larger IT projects and paused tenders all now back in progress. Supply issues are being closely monitored by working closely with our supply chain and working with multiple suppliers and partners.

Given the tricky headwinds created by covid the performance of the business over the covid period and as we move out of it has been excellent. When compared to the equivalent period pre-covid revenue is up 3.9% and with zero debt.

Equal opportunity

Equal opportunity

Equality and diversity
Redcentric actively supports the principle of equal opportunities in employment and is committed to ensuring that individuals are treated fairly, with respect and are valued. Redcentric opposes all forms of unlawful or unfair discrimination on the grounds of colour, race, religion or belief, nationality, ethnic or national origin, sex, gender reassignment, sexual orientation, marital or civil partner status, age, or disability (the "Protected Characteristics"). It is important to Redcentric that no one receives less favourable treatment or be disadvantaged on any of the above grounds. Every possible step will be taken to ensure that individuals are treated equally and fairly and that decisions on recruitment and selection and opportunities for training and promotion are based solely on objective and job-related criteria.
Gender Pay Gap Report
Our gender pay report at the snapshot date of 5th April 2021 showed that the overall difference between men and women’s earnings at Redcentric was 21% (mean) or 18% (median), based on hourly rates of pay at the snapshot date of 5th April. Like most organisations in our industry, the primary reason for our gender pay gap is an imbalance of male and female colleagues at different levels across the organisation. We are confident as we make progress towards achieving greater gender balance across all roles within Redcentric.
Learning and Development
We have a strong ethos of upskilling and supporting the development of our colleagues.
• Apprenticeship programmes - gain qualifications in networks, data storage, computing and electro-technical systems
• Work Experience Programme ‘Redcentric Set Go’ – allowing local students to gain experience within the workplace to enhance their skills and CV
• Learning Management System (Talent LMS) which allows employees to gain access to multiple training modules to enhance their development


At Redcentric, the wellbeing of our colleagues is incredibly important to us. Over the last 12 months we have introduced a whole host of wellbeing initiatives aimed at improving our colleagues mental and physical health.
Hybrid working model has allowed our colleagues more flexibility and encouraged them to gain work: life balance.
Our Wellbeing Channel hosts resources that support mental and physical health including webinars, mental health resources for children and recordings of our yoga and mindfulness sessions.
The Met Life Wellbeing Hub is available to all employees, providing a range of wellbeing support and access to services including therapy, counselling, legal and financial management information.
Linking in with our CSR strategy, we have created a Wellbeing calendar that highlights awareness weeks throughout the year, such as Men’s Health Week, Stress Awareness Week and World Mental Health Day. This is accessible on our Wellbeing Teams channel.
The Board leads by example with respect to promoting a healthy corporate culture and ensuring that ethical values and behaviours are embedded in the business. The processes in place for decision making which are documented in its committee terms of reference, the Company’s share dealing code and the requirement for regular disclosure of interests are all examples of processes which require high standards of behaviour from the Board.
Employment policies adopted by the Company, such as its whistleblowing and anti-bribery policies assist in embedding a culture of ethical behaviour and the values set out in its corporate social responsibility statement.
We’ve trained over 20 Mental Health First Aiders across the business with the aim of having at least one in every team and generate continuous engagement through planned initiatives. Our ‘Let’s Talk Service’ is a designated time in the diary each week for Mental Health First Aiders to keep free.
