2025 feels like a vital year for the cybersecurity industry. With Gartner anticipating cybersecurity spending rising 15% across the board this year, growing from $183.9bn to $212bn, protecting users online while maintaining operational resilience has never been more important.

Some specific sectors are becoming especially reliant on robust cybersecurity measures to counter the fast-evolving threats online.

Below, we explain why 2025 looks set to be a vital year for three industries in terms of cybersecurity and their unique challenges faced.

Healthcare

The global healthcare industry is becoming increasingly digitised. Many patients now have access to electronic health records, and the likes of telemedicine platforms and always-connected medical devices are now commonplace. The transition is designed to improve the transparency of patient care, but it’s not without its security risks.

In 2025, safeguarding patient data is a top priority. Ransomware attacks targeting hospitals and clinics are becoming more frequent, threatening to disrupt operations and compromise sensitive patient information. To counteract these threats, healthcare providers are increasingly investing in advanced threat detection systems and endpoint security solutions. These tools help identify and mitigate breaches before they can cause significant damage.

The healthcare industry also has the challenge of integrating cybersecurity measures which protect medical devices powered by the Internet of Things (IoT), ensuring life-saving devices cannot be tampered with or hijacked.

iGaming

The iGaming market, which encompasses online sports betting, casino gaming and other interactive gaming, has experienced huge growth in areas which have licensed and regulated markets. In the U.S. alone, there’s now millions of betters who entrust their sensitive data and funds in the hands of iGaming operators. The need for airtight cybersecurity couldn’t be any greater.

There are two critical aspects of an iGaming platform’s integrity and cybersecurity. First and foremost is the use of Secure Socket Layer (SSL) certificates. These are imperative to provide end-to-end encryption for players, giving users peace of mind when sharing their financial details.

The second is the integrity of decentralised random number generators (RNGs). RNGs are the backbone of online slots and classic casino table games, ensuring outcomes are fair and unpredictable. One of the best ways for players to win at slots is by looking for slot titles with high return-to-player (RTP) percentages. These are known as loose slots in the industry – specifically referring to RTPs over 96%. Online casinos must protect the integrity of their RNGs and ensure their games deliver the RTPs and volatility they are meant to.

Financial Services

The financial services sector has long been a prime target for cybercriminals due to the immense value of money and data. In 2025, the challenges have only grown more complex with the rise of cryptocurrency and digital banking.

Multifactor authentication (MFA) and biometrics are now standard for securing online transactions, providing customers with peace of mind when managing their finances. Beyond this, zero-trust architecture is becoming the norm, ensuring that every access request is verified and continuously monitored. Blockchain itself offers enhanced transparency and security for transactions, but it is not immune to vulnerabilities. Consequently, financial institutions are adopting sophisticated cryptographic techniques and threat intelligence platforms to safeguard their systems.

This trio of industries are some of the most fragile sectors due to the vast sums of money involved and the critical nature of patient data. Cybersecurity in 2025 is no longer a hurdle to overcome, but an imperative innovation to foster trust and enhance user experiences.
