5 Must-Have Cybersecurity Best Practices for Fintech Startups

As disruptors of the financial industry, you have targets on your backs for hackers who want access to the sensitive customer data you handle. Not to mention needing to comply with complex regulations right out of the gate. Building a secure system against threats can feel daunting when you're just a fledgling startup trying to get off the ground.

However, having robust cybersecurity practices baked into your company’s DNA from day one is non-negotiable. The last thing your business needs is a damaging breach that destroys customer trust. Think of security as an investment, not an expense.

There’s no doubt it’s tempting to focus solely on core product development early on. But seriously, you cannot afford to neglect cybersecurity - your business is literally at stake. So here are 5 must-have security best practices to implement immediately:

1. Lock Down Your Cloud Data and Access Controls

As a modern fintech startup, there's no way you're avoiding the cloud. Its flexibility, scalability, and collaboration are central to fast growth and innovation. But improperly configured cloud environments are vulnerable to breaches, data leaks, and theft of credentials granting access.

So step one is to lock down your cloud data security strategy right from day one. Here’s how:

• Enable multi-factor authentication (MFA) for accessing cloud admin consoles and resources. This adds an extra layer of protection beyond just passwords, which can be guessed or phished.
• Use cloud data encryption to scramble sensitive financial information. Encryption ensures prying eyes can't read essential data if they manage to exfiltrate it.
• Implement the least privilege access principle by only providing the absolute minimum permissions each team member needs to do their specific job. This limits damage from compromised credentials.

Additionally, ensure you understand your cloud providers' shared responsibility model. They secure the underlying infrastructure, but data security falls to you. So get clear on this delineation and check providers for independent audits and certifications that validate their physical and network security controls.

2. Institute Secure Coding Practices

The next critical element to prioritize is adopting secure coding techniques and standards from the get-go:

• Train your developers early on languages and frameworks like OWASP Top 10 and SANS Top 25 most dangerous coding errors and vulnerabilities. These educate on common weaknesses to avoid in areas like input validation, authentication, and encryption implementations.
• Establish secure coding standards, policies, and peer code reviews to enforce best practices across all your application development efforts. Doing so identifies bad patterns, errors, and omissions before they make it to production, where flaws become exploits.
• Push developers to "shift left" by testing code quality and finding security issues from the start of product ideation rather than just before launch. It's vastly more expensive to address vulnerabilities post-deployment.

Taking these steps immediately embeds security into your engineering culture rather than attempting to tackle it as an afterthought down the road.

3. Protect Yourself with Deception Technology

As a prime target for sophisticated hackers and fraudsters, you need proactive protection against threats that will inevitably infiltrate your defenses. Deception technology provides active cybersecurity measures to root out bad actors before they cause damage.

The concept uses decoys and traps to confuse and divert cyber criminals so you can detect credential compromises, malware infections, unauthorized lateral movement, and data exfiltration. Deploy decoy resources that look and act just like production assets so you can monitor access and alerts when abnormalities emerge. Other deception technology ploys include:

• Honeypots that simulate applications, network shares, and credential stores to study hacker behaviors and tools trying to interact with them.
• Poisoned data sets are mixed with real records to track misuse and confidentiality breaches if the fake data appears outside the organization.
• Booby-trapped computing resources that disable themselves or notify you if manipulated.

This powerful technology turns your infrastructure against malicious actors, shifting their typical asymmetric advantage to your favor.

4. Verify Third Party Security Posture

It's pretty much impossible for any modern fintech startup to avoid relying on a sprawling web of third-party vendors who provide critical business functions:

• Cloud hosting, storage, and computing platforms
• Financial service APIs and banking integrations
• Regulatory compliance and auditing
• Data analytics and ML algorithms
• Marketing automation and customer engagement

While it is extremely convenient to leverage the expertise of third-party providers, you essentially hand over bits of your attack surface to them. If those partners have weak security practices, this can severely impact you during a breach.

So, you simply must implement vendor risk management protocols to verify and continuously monitor the cybersecurity posture of all external parties you rely on. Make sure to:

• Establish data security terms in your supplier and partner contracts, allowing you to probe their controls.
• Independent audits and globally recognized security certifications are required before partnering.
• Continuously monitor their practices for changes and assess for new vulnerabilities.

Don't be blindsided if a small vendor in your ecosystem gets compromised.

5. Develop an Incident Response Plan

Even if you do everything else right, you have to be prepared for inevitable security incidents by having an incident response plan mapped out upfront:

• Designate key stakeholders across departments who will oversee investigation and remediation decisions during crises. Outline their roles and decision-making authority. Practice response plan scenarios through cybersecurity incident simulations to resolve issues.
• Formalize your procedures for detecting, reporting, and communicating threats following disclosure laws and customer expectations.
• Pre-negotiate relationships with cybersecurity insurance carriers, forensic investigators, crisis communications firms, legal counsel and possible law enforcement agencies who you will rely on if an incident occurs.
• Make sure you have the capability to rapidly re-secure or safely shut down compromised systems, roll back data from backups, and preserve forensic evidence.
• No one ever regrets overpreparing for the chaos of an actual crisis scenario. So get these emergency response ducks in a row early!

Ongoing Vigilance is Key

Don't interpret this advice as security "nice-to-haves" or gold-plated recommendations. They represent baseline best practices expectations today for any company handling financial data and transactions. Get these right first before moving onto more advanced security measures as you scale and you will set yourself up for success as you scale. And the best part is that you won’t need to continually look over your shoulder worrying about your next security breach.
