Are Your Third-Party Apps a Danger?

These days, businesses depend more and more on third-party apps for everything from customer service and analytics to cloud storage and security. While this is convenient, it comes with a risk. Every new app integration introduces a potential vulnerability. In fact, the recently released SecurityScorecard 2025 Global Third-Party Breach Report states  that 35.5% of all recorded breaches in 2024 were linked to third-party vulnerabilities – with another surge in 2025.

But don’t hit the panic button just yet - these risks can be managed and overcome. Let’s shine a light on the hidden dangers of third-party API integrations and provide a practical checklist to help you evaluate any external app before adding it to your system.

Are we supposed to be using 3rd party apps?

In concentrating on the core nature of your business, it’s not necessary to reinvent the wheel at every turn. Most businesses do not create each technology component from scratch, so the various tools you need are already there, and can be used safely. Relying on third-party apps and APIs can manage everything from payments to customer support, analytics, email automation, chatbots, and more. Third-party integrations boost efficiency, streamline operations, and improve overall productivity. The aim is to speed up development, cut costs, and gain access to features that might take months to build internally.

Hidden Risks

When you add third-party apps to your systems, you are inevitably inviting several risks, including cybersecurity, privacy, compliance, and operational and financial vulnerabilities. Let’s break the three major risks down:

1: Cybersecurity Risks

A seemingly harmless plugin may contain malware or malicious code that activates upon installation, potentially corrupting data or allowing unauthorized access. Once an integration is compromised, hackers can use it as a gateway to infiltrate your systems, steal sensitive information, or cause operational disruptions. Always look for apps with a reputation for strong security.

2: Compliance and Privacy Risks

A compromised third-party app can put your data at risk - even with strong contractual and technical controls. Vendors may gain access to sensitive information and use it in ways you never authorized, such as storing it in different regions, sharing it with other partners, or analyzing it beyond the agreed purpose. For instance, misuse of a platform could lead to violations of data protection laws, exposing your organization to legal penalties and reputational damage.

3: Financial and Operational Risks

When third-party integrations go wrong, they can affect both operations and finances. If an API fails or underperforms, it can disrupt workflows, cause outages, and impact service quality. Weak credentials or insecure integrations can be exploited, potentially leading to unauthorized access or costly financial losses.

How do I check if an app is safe?

The smart move before you connect any app, is to take a moment to give it a careful check-up. Use the ‘due diligence’ checklist below to make sure it’s safe, secure, and ready to work for you:

Scrutinize Security Credentials and Certifications: Research the app provider to ensure that it has solid, recognized security credentials, such as ISO 27001, SOC 2, or NIST compliance. Ask for audit or penetration test reports and see if they run a bug bounty program or have a formal vulnerability disclosure policy. These show the vendor actively looks for and addresses security issues before they become a problem.

Data Encryption is a MUST: Even if you can’t inspect a third-party app directly, you should review their documentation, security policies, or certifications like ISO 27001 or SOC. Ask the vendor how they encrypt data both in transit and at rest and make sure any data moving across networks uses strong protocols like TLS 1.3 or higher.

Modern Authentication & Access: Choose an app that uses state if the art standards like OAuth2, OpenID Connect, or JWT tokens. Confirm it follows the principle of least privilege, giving users only the access they truly need. Credentials should be rotated regularly, tokens kept short-lived, and permissions strictly enforced.

High-Level Monitoring & Threat Detection: Only consider apps that offer proper logging, alerting, and monitoring. Ask the vendor how they detect vulnerabilities and respond to threats. Once integrated, consider maintaining your own logs to keep a close eye on activity and spot potential issues early.

Look For Solid Versioning & Deprecation Policies: Your chosen API provider should maintain clear versioning, guarantee backward compatibility, and communicate when features are being retired or severely modified.

Limits & Quotas: Confirming that the provider supports safe throttling and request limits well help prevent abuse or system.

Demand the Right to Audit & Contracts: Be sure to protect yourself with contractual terms that allow you to audit security practices, request documentation, and enforce remediation timelines when needed.

Secure Data Location & Jurisdiction: You need to know where your data is stored and processed, and ensure it complies with local regulations.

Ask About Failover & Resilience: Find out how the vendor handles downtime, redundancy, fallback mechanisms, and data recovery, because no one wants surprises when systems fail.

Verify Dependencies & Supply Chain: Insist on a list of the libraries and dependencies the vendor uses, especially open-source ones. Assess them for known vulnerabilities to avoid hidden risks.

Frequently Asked Questions

Which third-party app is safe?

While no third-party app is guaranteed 100% safe, those from reputable sources such as the Apple App Store and Google Play Store are generally safe, as they are reviewed before being listed.

What is an API in apps?

API (Application Programming Interface) refers to any software with a distinct function, and Interface can be thought of as a contract of service between two applications. This contract defines how the two communicate with each other using requests and responses.

How does visioning work?

Visioning in general is a futures research method that involves creating detailed and aspirational images of the future, focusing on desired outcomes rather than predictions. In the world of apps, it means forecasting the future development of the app.

What does it mean to be NIST compliant?

NIST (The National Institute of Standards and Technology) compliance reinforces zero trust by offering risk-based controls, strong authentication, and continuous monitoring. It helps organizations verify every user and device, limit lateral movement, thereby strengthening the overall security posture.
