Information security policies and processes
The service is certified to a number of different standards, including ISO 27001:2013. This is based on an ISMS (Information Security Management System) which consists of Thales UK policy, process and procedures in addition to ISO 27001 clauses. The ISMS is audited by independent 3rd parties annually. An annual IA (Information Assurance) schedule ensures that policies are implemented, assessed and effective. This includes internal audits, external audits, Security Working Groups, Security Awareness campaigns. The reporting structure is defined in the Thales IA Management Plan, along with incident management processes and RACI matrix. The service assurance is also achieved through additional certifications and accreditations, which include audit reports being submitted to the Cabinet Office, NCSC and the National Police Information Risk Management Team (NPIRMT).

Operational security

Configuration and change management standard
Conforms to a recognised standard, for example CSA CCM v3.0 or SSAE-16 / ISAE 3402
Configuration and change management approach
All Requests for Change (RFC)’s are presented to a Thales’ Change Board (CAB). The CAB is attended by Business, Technical, Service Delivery and Information Assurance stakeholders along with the owner of the RFC’s. On receipt of a request to make changes to the service; an RFC will be generated and submitted to CAB prior to delivery. Changes will be notified to customer CABs where there is a change to the device(s) which may impact service.
Vulnerability management type
Conforms to a recognised standard, for example CSA CCM v3.0 or SSAE-16 / ISAE 3402
Vulnerability management approach
The Thales SOC utilise an IBM vulnerability management module to prioritise vulnerabilities. The Thales SOC also utilise various threat intelligence and vulnerability feeds to stay informed of the latest vulnerabilities. The SOC then advises on recommended activity and mitigations.

As part of the Thales compliance requirements, Thales has a requirement to be able to adequately respond to Low to Critical level patches and vulnerabilities.
Thales Change Management is then used to apply patches in a managed and timely manner – to prevent disruption to customer services
Protective monitoring type
Conforms to a recognised standard, for example CSA CCM v3.0 or SSAE-16 / ISAE 3402
Protective monitoring approach
The Thales SOC provides protective monitoring and threat intelligence to identify potential compromises, cyber-attacks and non-compliance.
The SOC follow processes and escalation paths in response to potential compromises and security incidents. A severity matrix is used to assign a priority to each incident. The priority determines the response for the incident. Agreed stakeholders and contacts are contacted depending on the severity.
Incidents are responded to within SLA – in accordance with the assigned priority.
Incident management type
Conforms to a recognised standard, for example, CSA CCM v3.0 or ISO/IEC 27035:2011 or SSAE-16 / ISAE 3402

Fighting climate change

Fighting climate change

Thales UK has a clear focus on fighting climate change. Thales has set itself a target of becoming a Carbon Net Zero company by 2030, powered by cleaner energy used more efficiently at our sites and for our business, with renewable energy supplies.

There are several strategies that Thales and our Cyber offerings implement to fight climate change, including:

1) Sustainable future. Thales has put fighting climate change at the centre of its strategy, highlighted by the fact that tackling climate change is one of the 4 Thales strategic pillars. Thales Cyber security and consultancy offerings have enabled companies to develop secure and sustainable products, prevent product recalls, learn digital lessons and reduce rework that go towards meeting their strategic sustainability objectives and tackle climate change.

2) Travel reduction. Thales has introduced a Smart Working model to reduce the travelling required by the workforce. One pillar of this is arranging virtual meetings with Customers, Stakeholders and interested parties. Thales has also deployed numerous tools to enable Thales UK to effectively operate via remote / smart working. It is expected that meetings under G-Cloud could implement this methodology to offer the same benefits to the customer. Running on managed services means efficient use of shared and common infrastructure, allowing sustainable collaboration from existing infrastructure, where organisations or teams may once have had dedicated infrastructure are now allowed to work remotely, securely.

3) Carbon reduction. Thales strives to implement carbon reduction, through a series of targets to reduce carbon emissions annually. Smart working, championed by our Cyber Security Consultants and offerings has been a key enabler of this strategy. Additionally, services enabling secure collaboration mean that businesses do not need to procure additional new hardware, thereby having a positive environmental impact.
Covid-19 recovery

Covid-19 recovery

Thales has put a clear focus on a UK-wide recovery from the Covid-19 Pandemic.

Throughout the pandemic, Thales UK responded as a member of the Ventilator Challenge UK consortium, which brought together companies from the Aerospace, Automotive, Medical and other sectors to deliver more than 13000 ventilators in response to the pandemic. This demonstrated that Thales UK was able and willing to mobilise its capabilities, resources and know-how, to be among the first to respond to the national emergency as an integral part of the UK’s critical national infrastructure and strategic supply chain, was formally recognised by HM government and led to an award for pandemic service.

Throughout and since the Covid-19 pandemic there has been a concerning rise in Cyber security threat with sector specific cyber-attacks being directed towards a number of critical infrastructure sectors. Thales’ cyber security offerings provide protection from these threats and have been provided to key services including the NHS, allowing national recovery from the pandemic. Thales Secure connectivity services and cyber consultants allow these key businesses and Critical National Infrastructure to have secure options in connecting and sharing securely with 3rd parties to recover and grow safely from the COVID 19 Pandemic.

In addition, Thales will continue to provide sustained and additional employment opportunities in high-skilled, high value, aspirational careers critical to national and business security that support future regional and national growth. This includes cyber specialists and consultants in regions across the UK, such as Doncaster and Ebbw Vale.
