Dacros is your outsourced IT department for Doncaster businesses: proactive support, hardened cyber security, and the networks and phones behind them. One accountable partner, one predictable monthly plan.

Coverage

Technology support for Doncaster businesses

Dacros works with businesses across the UK. Most of the work is done remotely, and on-site work is by arrangement. That includes businesses in Doncaster and nearby, such as Armthorpe, Thorne and the DN postcodes.

Whether you are a Doncaster office of a handful of people or an organisation across several sites, the groundwork is the same: security settings switched on from day one, devices and backups monitored, and every change written down. The plan is then sized and priced to the business you actually run.

On-site: By arrangement
Remote: Across the UK
Scope: Business IT and cyber security. Nothing else.

What we cover in Doncaster

Everything technology touches

Six things, and no more than six, under one roof with one accountable point of contact. A typical Doncaster engagement begins with the first two.

01 Managed IT supportCore Helpdesk, monitoring and patching, your email and files looked after and moved to European providers when you are ready, and backups that get tested rather than assumed. 02 Cyber securityCore Reviews, Cyber Essentials readiness, email-fraud protection, multi-factor authentication and backups. 03 Networks and Wi-Fi Business Wi-Fi, firewalls configured rather than plugged in, secure remote access and multi-site connectivity. 04 Telecoms and VoIP Cloud phone systems that work in the office, at home and on a mobile, on one number. 05 Data cabling Structured cabling for Doncaster office moves, fit-outs and expansions, tested and labelled. 06 Remote support Attended remote sessions for the things that do not need somebody in the building.

City of Doncaster Council and national services

Local help for Doncaster businesses

Doncaster is in City of Doncaster Council's area, in South Yorkshire. These are public services and local business bodies that any Doncaster business can use, whoever looks after its IT; Dacros has no connection with any of them.

01
Business support in Doncaster

Business Doncaster, the council's inward investment team, gives free and confidential help with business support, investment, land and property, economic intelligence and supply chains, to businesses of any size or sector, with start-up and growth support and business forums (01302 735555). The South Yorkshire Growth Hub helps businesses find support with skills and training, finance, innovation, exporting and starting up; its Skills Bank programme is funded by the South Yorkshire Mayoral Combined Authority, which brings together Barnsley, Doncaster, Rotherham and Sheffield. Each of the four councils runs the Business Productivity and Digitisation Grant Scheme for its own area.
02
Free cyber security help

GOV.UK lists nine regional Cyber Resilience Centres: police-led, not for profit, supporting businesses of all sizes, with a free membership package among the options. The NCSC's free tools need no specialist: Check your cyber security tests your website, email security and web browser with no registration, Early Warning sends any UK organisation notifications of malicious activity, and the Cyber Action Toolkit is a free, personalised toolkit for sole traders, micro businesses and small organisations.
03
Broadband in Doncaster

The centre of Doncaster is in the Doncaster Central constituency. In Ofcom's figures for January 2026, full fibre was available to 97.3% of premises there, homes and businesses together, and gigabit-capable broadband to 97.8%, while 0.7% could not get 30 Mbit/s. Across the City of Doncaster the figures were 94.5%, 96.4% and 0.7%. Business premises often lag behind: across England, 70.9% of business premises had full fibre, against 82% of homes. Ofcom's checker shows what your own address can get, so you can tell whether a slow connection is the line or the equipment.
04
If a scam or a cyber attack reaches the business

Doncaster Trading Standards gives local businesses regulatory advice and points them to Business Companion for free legal guidance; scams and rogue traders are reported through Citizens Advice, online or free on 0808 223 1133. If the business loses money or is hacked through a scam, report it to Report Fraud, the police service that replaced Action Fraud, online or on 0300 123 2040, Monday to Friday, 8am to 8pm. Forward a suspicious email to report@phishing.gov.uk and a suspicious text, free, to 7726. The NCSC's Where to report a cyber incident service says who else you need to tell, and a personal data breach that puts people at risk must reach the ICO within 72 hours of your becoming aware of it.

Checked on 8 November 2026 against the pages linked above. Broadband figures are Ofcom's for all premises, homes and businesses, in January 2026, from the Connected Nations update: Spring 2026, published 13 May 2026.
