For a high-growth startup, the biggest security risk is not always a dramatic cyberattack. It may be a rushed hire who retains access after leaving, a supplier with weak controls, an investor conversation that reveals too much, or a founder using a personal device late at night after the school run.
That is why the UK government’s Secure Innovation Security Reviews deserve the attention of startup leaders. The programme was designed to give early-stage technology businesses tailored, practical advice on protecting intellectual property, people, systems and commercial advantage from threats including cybercrime, insider risk and hostile competitors.
There is one important date to clarify before founders make plans: the published Innovate UK Business Connect page says the most recent application window opened on 10 July 2025 and closed on 31 January 2026. So this is not currently an open call to join. However, the programme remains a valuable model for founders preparing for a possible future round, seeking other security support, or simply trying to build a company that is safer, more investable and harder to disrupt. Read the official scheme details from Innovate UK Business Connect.
For busy business owners, including parents managing a company around care responsibilities and migrant founders building a network and business in a new country, the message is not “add another complicated compliance project”. It is “make a few focused decisions now, before growth makes them expensive and difficult to reverse”.
What were Secure Innovation Security Reviews?
Secure Innovation is a campaign delivered in the UK by the National Protective Security Authority and the National Cyber Security Centre. It is aimed at emerging-technology businesses whose ideas, research, data and commercial plans may be attractive to criminals, competitors or state-backed actors.
The Security Review scheme offered a high-level assessment by an approved security professional. It looked beyond passwords and antivirus software. The review covered protective-security governance, security culture, risk management, cyber security, supply chains and partnerships, and incident management. The intended outcome was a bespoke set of recommendations that a startup could incorporate into its wider business strategy. Explore the NPSA Secure Innovation resources.
That broad scope matters. A life-sciences company might secure its lab data but overlook what happens when research is discussed at a conference. An AI startup may protect its cloud environment but grant every contractor access to training data, model weights or source repositories. A renewable-energy venture could conduct sensible cyber checks while failing to assess whether a critical overseas supplier presents operational or information-security risk.
Security is therefore not a standalone IT task. It is a business discipline that helps preserve the thing that makes a startup valuable: the ability to turn a hard-won insight into a sustainable commercial advantage.
Why this matters to high-growth startups
Startups move quickly by design. Founders hire, sign pilots, outsource work, enter new markets and pitch investors with limited time and cash. Those are necessary growth activities, but each can create new routes to sensitive information, systems and decision-making.
The NCSC warns that small organisations should not assume they are too small to be targeted. Its current small-organisation guidance states that one in two small businesses suffers a cyber incident every year, and stresses that cyber security is everyone’s responsibility rather than the job of one technical employee. Use the NCSC’s small organisations cyber security guide.
For an ordinary small business, a cyber incident can mean lost time, interrupted sales and reputational damage. For a scaling innovator, the stakes can be even higher. A stolen design, unpublished dataset, manufacturing specification, customer roadmap or clinical research result can weaken a funding round, delay a launch or erase the advantage built by a small team over many months.
Security also has a human dimension. A founder who is exhausted, travelling frequently or balancing business and family may understandably choose the quickest route: sharing a file through a personal account, approving access without checking it, or postponing device updates. These are not personal failings. They are predictable pressure points in a demanding business. Good security removes friction through clear, repeatable processes, so the secure route is also the easiest route.
Migrant founders may encounter extra complexity when establishing banking, suppliers, legal support, overseas collaborators and new hires across borders. International networks are often a commercial strength, not a weakness. The practical issue is to apply consistent due diligence to every relationship, regardless of where a contact is based or how warmly they were introduced.
The threats a review is built to uncover
Insider risk is not only about malicious employees
Insider risk includes deliberate wrongdoing, but it also includes mistakes, unmanaged access and poor offboarding. A well-intentioned employee might email code to a private address to work over a weekend. A departing contractor may still be able to open a shared drive. A founder may give a new recruit broad access “just for now” and never revisit it.
The government’s launch announcement specifically highlighted stronger checks on prospective employees as a way to reduce insider threats. It also noted that personnel, physical and cyber security need to work together rather than being treated as separate issues. Read the government announcement on Secure Innovation Security Reviews.
This does not mean creating a suspicious workplace. It means defining what information is truly sensitive, limiting access to people who need it, documenting decisions, and making joining and leaving procedures consistent. A positive security culture encourages people to report a mistaken email, lost device or unusual request early, without fear of embarrassment.
Cyberattacks target ordinary weaknesses
Many attacks do not begin with sophisticated espionage. They begin with a phishing email, a reused password, an unpatched device, a fake invoice or an exposed cloud account. The NCSC describes Cyber Essentials as the government-recommended minimum cyber-security standard for organisations of all sizes, based on five technical controls against common internet-based threats. See the NCSC overview of Cyber Essentials.
That makes baseline cyber hygiene an operational priority, not a future aspiration. Use multi-factor authentication on email, finance, source-control and cloud accounts. Maintain an inventory of company devices. Apply updates promptly. Use a password manager or passkeys where suitable. Keep tested backups. Create a simple route for reporting suspicious messages. These measures are unglamorous, but they protect the hours founders would otherwise lose responding to a preventable incident.
Partnerships can expose more than founders expect
Startups depend on outside relationships: universities, manufacturers, freelancers, cloud providers, agencies, distributors, investors and larger customers. Each relationship can bring expertise and opportunity. It can also create dependencies and information-sharing risks.
The NPSA’s company guidance advises startups to conduct independent supplier due diligence, build resilience where there is overreliance on one supplier, and include security responsibilities in contracts from the outset. Read NPSA guidance for innovative companies.
In practical terms, do not send an entire technical data room merely because someone has signed a standard non-disclosure agreement. Share in stages. Use a clear purpose for each disclosure. Check who will access the material, where it will be stored and whether subcontractors are involved. Ask what happens to your data at the end of the engagement. These are commercially sensible questions, not signs that you are difficult to work with.
Who the scheme was for and whether your startup would have fit
In the latest published round, the scheme was aimed at UK-registered, trading SMEs with fewer than 250 people. Applicants needed to contribute £500 including VAT towards a £3,000 review, with £2,500 funded through the scheme. They also had to commit staff time, complete the process and take part in a six-month follow-up.
Eligible businesses needed to work in one of the 17 sensitive areas listed under the National Security and Investment Act or in selected Industrial Strategy areas. The published list included artificial intelligence, advanced materials and semiconductors, energy, computing hardware, quantum technologies, synthetic biology, transport, advanced manufacturing, clean energy industries and life sciences. The former scheme was limited to 500 businesses and funding was described as first come, first served for eligible applicants.
If a similar round opens, a startup is likely to be a strong candidate if it has valuable intellectual property, commercially sensitive research, a product with dual-use potential, international growth plans, a complex supply chain, or an expanding workforce. Spinouts and startups with substantial growth potential were specifically identified as relevant to the scheme.
Yet founders should not wait for a grant to become security-minded. A review is an accelerator for good decisions, not a substitute for leadership. If your startup would be materially harmed by losing a key dataset, codebase, manufacturing drawing, customer list or research insight, then security deserves a place on the leadership agenda now.
How to prepare for a future review
1. Identify your crown jewels
Begin with a simple question: what would damage the business most if it were stolen, altered, leaked or unavailable for a week? The answer may be different from the largest file or most expensive system.
- For an AI company, it could be proprietary datasets, model architecture, evaluation results, source code and customer prompts.
- For a biotech venture, it could be research protocols, samples, trial data, patent strategy and laboratory systems.
- For a semiconductor or advanced-materials startup, it could be designs, process parameters, prototypes, test results and specialist equipment access.
- For a clean-energy company, it could be engineering drawings, grid data, supplier pricing, project pipeline information and control systems.
Write these assets down. Note where they are stored, who can access them, which third parties touch them and what would happen if they were unavailable. This turns vague concern into a manageable risk register.
2. Appoint a named security owner
A startup does not need a full-time security executive on day one. It does need someone with enough authority to make security visible. This may be the CEO, COO, CTO or a board member, depending on the business.
The owner should bring a short update to leadership meetings: key assets, new suppliers, major access changes, incidents, upcoming travel and the top actions due. The aim is not bureaucracy. It is to stop security becoming an orphaned task between IT, HR, legal and operations.
3. Map access before hiring accelerates
Make a list of your major business tools, then ask who has administrator rights, who has access to sensitive folders and which accounts belong to former workers. Remove unnecessary permissions. Set a rule that access is granted by role, reviewed periodically and removed on a defined timetable when someone leaves.
Create a joining checklist and an exit checklist. Include company devices, email, cloud storage, finance tools, customer systems, passwords, code repositories, physical keys and confidential information. A five-minute checklist is more reliable than memory during a busy hiring month.
4. Strengthen the basics before buying expensive tools
Many founders assume “security” means purchasing a complex platform. Start with the fundamentals: multi-factor authentication, software updates, device encryption, backups, appropriate admin rights and staff awareness. The NCSC also provides free, short online training for employees covering passwords, device security, phishing and incident reporting. Share NCSC Top Tips for Staff with your team.
If you use an external IT provider or managed service provider, make sure the contract spells out responsibilities. Ask how they protect administrator accounts, manage backups, notify you of incidents, handle staff access and support you if your business grows or changes provider.
5. Prepare for an incident while calm
Every startup should know who makes decisions if a key account is compromised, a laptop disappears or sensitive data is sent to the wrong recipient. Keep essential contacts, recovery steps and communication responsibilities in one accessible place. Test the plan with a short tabletop exercise: “It is 8am on Monday and the finance mailbox has been taken over. What do we do in the first hour?”
The NCSC’s small-business response and recovery guidance sets out preparation, identification, resolution, reporting and learning stages. Use the NCSC response and recovery guide to build your plan.
Make security workable for a busy founder
The best security plan is one that survives a hectic week. Set aside a focused 60-minute session each month rather than promising an unrealistic overhaul. One month, remove ex-staff access. Next month, turn on multi-factor authentication everywhere. Then review backups. Then check supplier agreements. Small, consistent improvements compound.
Keep policies short and written in plain English. If your startup has team members whose first language is not English, avoid relying on dense legal or technical language alone. Explain the “why”, give examples, make reporting simple and invite questions. Security culture is stronger when people understand the business value they are protecting.
The NPSA’s free Secure Innovation Action Plan is a sensible starting point: it contains 25 questions across six sections and is designed to take roughly two minutes to complete. It will not replace expert advice, but it can help a founder spot gaps and prioritise next steps. Complete the Secure Innovation Action Plan.
Security is a growth enabler, not a brake
Founders are right to protect speed. But unmanaged security risk can be the fastest way to lose it. A breach can halt product work, distract the leadership team, unsettle customers and complicate fundraising precisely when momentum matters most.
The Secure Innovation Security Reviews programme showed that government and national security bodies see protective security as part of building a stronger innovation economy. While the latest published application round closed on 31 January 2026, its core lesson remains timely: protect the innovation while it is still young, valuable and easier to secure.
Call to action: This week, identify your three most valuable assets, name one person accountable for security, and complete the free Secure Innovation Action Plan. Then monitor the official Innovate UK Business Connect page for any future Security Review opportunity. The goal is not perfect security overnight. It is a startup that can grow with greater confidence, protect what makes it distinctive and give investors, customers and employees more reason to trust it.
