The Evolving Role of Cybersecurity in DeFI: How to Enhance Safety in 2025?
Cast your mind back to the 1990s, and the word “security” would typically evoke images of a bodyguard offering physical protection or the common-sense practice of not carrying too much cash to safeguard finances. However, the emergence of the internet added a new dimension to the equation — cybersecurity and as decentralized finance (DeFi) continues to disrupt traditional systems, the cybersecurity challenges it faces have grown equally dynamic. While the composability and permissionless nature of DeFi fuel innovation, they also create systemic risks that demand a proactive and evolving security framework. Let’s explore the world of Cybersecurity and how the ecosystem along with you the users can safeguard your digital assets in 2025!
Cybersecurity and its Pivotal Role
The Internet changed a lot of aspects in our life from the way we communicate with one another to the way information is easily displayed on our smartphone. One of the most important revolutions is how our finances have changed through the years where cash transactions are rapidly disappearing and being replaced by debit cards or mobile payments. Digital wallets, online banking, and contactless transactions have become the norm, offering speed and convenience but also introducing new risks.
Financial Security back then in the 1990s was rooted with a brick and mortar traditional system of institutions and paper-based transactions. As money then moves into the digital realm, so too the growing need of enhancing security from threats in the internet and ushering in a new era where cybersecurity is no longer optional, but essential for safeguarding our financial lives. It was around this period that the term “cybersecurity” began gaining traction. While the concept existed in earlier forms, the actual term “cybersecurity” is widely attributed to the work of computer security pioneers in the late 1980s and early 1990s — most notably credited to the U.S. Department of Defense and early cybersecurity researchers like Donn B. Parker.
The rise of online banking in the late 1990s and early 2000s then marked a critical turning point where Financial Institutions and Banks became the first early adopters of Cybersecurity. As Customers evolve to now manage transactions over the internet and enhance convenience, Bad Actors also have evolved to become Cybercriminals who quickly adapted, exploiting weak passwords, unsecured networks, and social engineering tactics to steal personal data and access financial accounts.
The rise of mobile devices and social media in the 2010s then further complicated the landscape, creating new vulnerabilities and attacks transformed on a larger scale to major corporations and even governments. One such high profile case include JPMorgan Chase — one of the largest financial institutions in the United States — suffered a massive cyberattack in 2014 that compromised the data of over 76 million households and 7 million small businesses.
In response, the attack highlighted how important Cybersecurity is in our daily life and Institutions invested heavily in layered defense mechanisms such as firewalls, encryption and multi-factor authentication just to name a few. It also exposed the truth that every User must take regular precautions in their own finances like changing password regularly and denying access to phishing scams because a Single Vulnerability can turn catastrophic if not properly tackled.
This also marked a step into other alternatives that would enhance security and reduce reliance on Central intermediaries altogether. This is where decentralized finance, or DeFi, began to emerge — not just as a technological innovation, but as a philosophical response to the fragility of centralized systems. Built on Blockchain Technology, the DeFI Space promised a permissionless, automation, and transparent network that should be promising in elevating security.
However as DeFI Space continues to grow, decentralization doesn’t eliminate risk — it merely changes its shape. In the Wild — West of DeFI Space, its “trustless” nature ironically requires users to trust that protocols and Smart Contracts are secure but without a Central Authority to actually vet the code, it led to many vulnerabilities. A prime example is the $120 million BadgerDAO hack in 2021, where attackers injected malicious scripts into the platform’s user interface to trick users into signing unauthorized transactions. Unfortunately unlike the Centralized Traditional Systems, it may be hard to recover or reimburse once funds are lost in DeFI.
Moreover, the composability of DeFi — where different protocols interact like modular building blocks — can also introduce cascading risks. A vulnerability in one protocol can be exploited to impact others in a chain reaction. For example, the Wormhole bridge hack in 2022, which resulted in over $320 million in losses and as DeFi continues to scale in 2025, these risks are compounded by the increased complexity of cross-chain integrations, anonymous development teams, and unvetted open-source code.
Cybersecurity in DeFi, therefore, requires a radically different approach — one that combines real-time auditing, community-driven oversight, decentralized insurance, and secure-by-design principles to ensure the resilience of this new financial frontier. In a system with no customer support hotlines, no centralized dispute resolution, and often no safety nets, the responsibility for security shifts directly to the protocol level and the end user.
Therefore every DeFI project must be proactive in its perspective towards security by conducting rigorous secure coding practices and thinking constantly. DeFI Platforms must implement permissionless, real-time monitoring systems and adopt defense-in-depth strategies that anticipate rather than react to threats. Cybersecurity at the end must also be a Shared Responsibility, end users must educate themselves on basic operational security to help safeguard their digital asset holdings. In 2025 and beyond, security will be a priority for everybody within the DeFI Space — not just to protect capital involved, but to uphold the very trust on which decentralization is built upon.
Enhancing Safety
Cybersecurity and Safety of all our Digital Assets is the responsibility of everyone within the DeFI Space, that is why it is always important to equip proper security in the platform you are using. Some of the most basic security measures will be creating a Strong Password that is hard to trace and avoid sharing your access to anyone that is involved as you might never know who the bad actors want to compromise your Digital Asset.
In almost every platform within the DeFI Space, measures such as KYC/AML have become mandatory to avoid any other person impersonating you as the Account Owner and taking possession of your Digital Asset so do complete your KYC process to enhance safety of your Digital Wallet. Another step towards a Secure Wallet is the 2FA Authentication System which is available in most platforms including your Nagaya (s) Wallet as the Authenticator App connected to your Registered Email Address will generate a random code every 30 seconds and deter any bad actors from accessing your Wallet. You may consider activating it if you haven’t!
Finally the most common steps to Cybersecurity is to prevent Phishing scams which happen very often within the DeFI Space and to secure yourself, avoid clicking any link in a random email or text message from people you are not aware of. Another Important Step is to activate the newest addition on your Nagaya (S) Wallet which is “NGY Lock!”, a revolutionary security measure that will help protect your HODLing Journey with Nagaya!
‘NGY Lock!’ acts as a shield to protect your NGY (BEP20) tokens from unauthorized outgoing transfers. Once activated, the NGY (BEP20) balance in your Nagaya (S) Wallet will be locked for the next 30 days to safeguard your HODLing experience. To further secure your Nagaya (BEP20) within your Nagaya (S) Wallet, cannot be deactivated anytime before the 30-day period is up. This feature is optional and available within your Nagaya (S) Wallet, for more information you can visit us at www.nagaya.co
Or you can download the Nagaya (S) Wallet app available on Google Play Store through the link below
