Ecommerce Security & Compliance: Safeguarding B2B Transactions in 2025

Jun 2, 2025

B2B eCommerce security in 2025 is more important than ever. By the end of the year, 80% of B2B sales will be conducted onlineconstructor.com. That’s a massive digital shift – and with it comes massive responsibility to keep those transactions safe. In B2B, a single order can be worth hundreds of thousands of dollars and involve sensitive contract terms. These high stakes make B2B eCommerce platforms a prime target for cybercriminals. B2B transactions often contain sensitive pricing, contracts, and financial data that must be zealously protected to maintain client trustconstructor.com.

At the same time, cyber threats are escalating. Ninety percent of companies say their cybersecurity risk increased in the last yearpymnts.com. Global eCommerce fraud is surging too – losses were an estimated $41 billion in 2022 and are projected to exceed $48 billion in 2023b2b.mastercard.com. The cost of a breach is staggering (the average breach now costs about $4.9 millionibm.com), not to mention the reputational damage that can permanently erode hard-won B2B client relationships. In this climate, security and compliance aren’t “IT problems” – they’re mission-critical business issues. If your B2B eCommerce site goes down from an attack or leaks data, large contracts and customer trust are on the line.

So how do you safeguard B2B transactions in 2025? First, it’s important to understand the major security and compliance concerns facing B2B eCommerce businesses today. Then, we’ll dive into a 5-step checklist of actionable measures you can take this quarter to boost your security. Let’s get into it.

Major Security & Compliance Concerns for B2B eCommerce

B2B eCommerce comes with unique security challenges. Here are the biggest areas to watch:

These concerns make it clear that B2B eCommerce security and compliance is a multifaceted challenge – from technical safeguards to legal requirements. The good news is there are concrete steps you can take to address each of these areas. Below is a five-step checklist of practical actions you can start right now to significantly improve your security posture.

Actionable 5-Step Checklist to Boost Ecommerce Security This Quarter

1. Enable and fully leverage Adobe Commerce’s built-in security features (firewalls, WAF, admin ACLs). Make sure you’re using all the security tools at your disposal on your eCommerce platform. If you’re on Adobe Commerce (Magento), that means turning on its built-in Web Application Firewall (WAF) and configuring it properly. Adobe Commerce’s cloud infrastructure includes a managed WAF powered by Fastly, which filters out malicious traffic based on known threat patterns experienceleague.adobe.com. This can automatically block a wide range of attacks – SQL injection, cross-site scripting, malware uploads – before they hit your site. Verify with your hosting provider or Adobe support that your WAF is active and tuned. Next, lock down your admin panel and backend: use a custom admin URL (not /admin), set up IP allowlisting or VPN access for the admin if possible, and enforce strong unique passwords. Most importantly, follow the principle of least privilege with admin accounts. Give each user the minimum access needed for their role – Adobe Commerce lets you configure fine-grained Admin ACL (access control lists) for this. For example, your content editor shouldn’t have access to payment settings. Limiting privileges minimizes damage if an account is compromised experienceleague.adobe.com. Additionally, enable CAPTCHA on login pages and consider rate-limiting or IP blocking to thwart brute force attacks. These built-in features are low-hanging fruit; it’s critical to actually turn them on and configure them correctly. If you’re not sure how, work with your developers or a security-focused agency. (At Creatuity, we ensure every Adobe Commerce build has these defenses in place from day one.) Taking full advantage of your platform’s security features creates a strong first line of defense.

2. Commit to regular patching and updates (stay current, or use Adobe’s SaaS auto-update model). One of the simplest ways to get hacked is running outdated software. Many attacks succeed by exploiting vulnerabilities that have already been fixed in later updates. Don’t give attackers that opportunity. Keep your eCommerce software, extensions, and server OS up to date at all times. Adobe releases security patches for Adobe Commerce on a routine basis (usually quarterly, with hotfixes as needed). Make it a habit to apply those patches as soon as they come out experienceleague.adobe.com. If you’re using open-source Magento, follow the Magento release announcements. For Adobe Commerce Cloud customers, take advantage of any tool that alerts you to new patches (Adobe’s Security Scan service can notify you of available updates experienceleague.adobe.com). Even better, Adobe Commerce has introduced a new “versionless” SaaS cloud model where the platform is always up to date for you – no more manual upgrades. With this cloud service, retailers are automatically kept on the latest version with all security patches applied by Adobe ranosys.com. In other words, Adobe handles the heavy lifting of updates so you don’t fall behind. Whether you’re on that model or not, you must also update any custom code or third-party integrations regularly. Designate a consistent patch schedule (e.g. monthly or quarterly maintenance windows) and stick to it. It helps to have a partner responsible for this; for instance, Creatuity prioritizes managed updates for our clients, applying patches often within days of release. The faster you patch, the smaller your window of vulnerability. Bottom line: update, update, update – it’s one of the most effective ways to prevent breaches.

3. Enforce two-factor authentication (2FA) for all admin users. If you do only one thing to secure user accounts, do this. Two-factor authentication adds an extra one-time code (from a mobile app or SMS) on top of the password for login. It’s a simple step that stops the vast majority of automated account hacks. Why? Even if an attacker steals or guesses an admin password, they can’t get in without that second factor. Adobe Commerce has built-in support for 2FA on admin accounts and even requires it by default on newer versions experienceleague.adobe.com. Make sure every single person with admin access is using 2FA, no exceptions. This includes developers, integrators, or anyone with an account on your eCommerce backend. It only takes a few minutes for each user to set up a 2FA app (like Google Authenticator or Authy), and it dramatically improves security. Yes, it’s an extra step at login, but admins don’t log in that often – and the trade-off in protection is absolutely worth it. Many high-profile breaches start with an admin credential compromise. 2FA renders those credentials almost useless to attackers. Along with 2FA, remind your team never to reuse passwords and ideally use a password manager. At Creatuity, we mandate 2FA on all client sites we manage because we’ve seen how effective it is. It’s one of the cheapest, easiest security wins, so deploy it everywhere you can (including other systems like your ERP, CRM, or any SaaS tools connected to your store). Your future self will thank you.

4. Conduct regular security audits and penetration tests. You can’t fix what you don’t know is broken. Regular security audits – both automated and human – are essential for finding vulnerabilities in your eCommerce environment before the bad guys do. Aim to conduct a thorough security audit at least annually, and ideally once a quarter given the pace of new threats. This should include code reviews (to spot things like SQL injection flaws or unsafe file upload functions), configuration checks, and vulnerability scanning of your site and servers. Equally important is penetration testing : hiring security professionals to simulate attacks on your system. They will use the same techniques hackers would, probing your site for weaknesses. Pen testers often discover logic flaws or edge cases that automated scanners miss. According to the latest PCI DSS 4.0 standard, businesses handling credit cards must do internal and external pen tests at least once a year and after any major changes datadome.co – so consider that the bare minimum datadome.co. Many experts recommend quarterly scans and annual pen tests for eCommerce. If you had a significant code update or integration, do an extra test afterward. Also, don’t neglect simple things like regularly reviewing user access logs and setting up intrusion detection alerts. If something does slip through, you want to catch it fast. In practice, it helps to partner with specialists for this. Our team at Creatuity conducts routine security audits for the stores we build, and we work with certified third-party auditors for independent penetration tests. The outcome of each audit is a report of concrete fixes – maybe a misconfigured server setting, an outdated library, or overly permissive admin access – which we then resolve. By proactively auditing and testing , you stay one step ahead of attackers and continuously strengthen your defenses. It’s an ongoing process, but it’s far better than waiting until after an incident to find out where your weaknesses are.

5. Ensure compliance with accessibility and data regulations (ADA/WCAG, GDPR, CCPA, etc.). Security isn’t just about keeping hackers out; it’s also about following rules that protect your users and your business. Two key compliance areas to focus on are web accessibility and data protection :

By focusing on both security measures (steps 1–4) and compliance measures (step 5), you create a holistic shield around your B2B eCommerce business. These efforts go hand in hand – for example, keeping software updated (step 2) helps prevent data breaches that could cause GDPR violations, and accessibility improvements (step 5) can enhance site usability for everyone. It’s all part of being a mature, trustworthy online B2B vendor.

Conclusion: No Time to Wait on Security

The rising importance of B2B eCommerce in 2025 means security and compliance can’t be an afterthought. Threats are growing, and so are the expectations from clients and regulators. The good news is that by taking action now – following the checklist above – you can dramatically reduce your risk. Each of the five steps is doable with a modest investment of time and resources, especially when compared to the cost of a security failure or compliance penalty.

Remember, security is an ongoing process, not a one-and-done project. It might feel overwhelming, but you don’t have to tackle everything at once. Start with the basics (like enabling 2FA and applying any outstanding patches) and build from there. In our experience at Creatuity, making security a habit – part of your regular website operations – is the key. We prioritize security and compliance in every Adobe Commerce project through managed updates, routine audits, and development practices that bake in protections from the ground up. The result is Adobe Commerce compliance with industry standards and peace of mind for our clients.

B2B eCommerce is booming, and with the right security posture, you can seize that growth safely. Use the next quarter to implement these steps. Assign owners, set deadlines, and get it done. Your future self (and your customers) will thank you. In an era of larger transactions and heightened cyber threats, a secure and compliant eCommerce platform isn’t just prudent – it’s a competitive advantage. So strengthen your defenses now, and move forward with confidence that your B2B transactions are safeguarded in 2025 and beyond.

Stay safe, stay compliant, and happy selling!
