Secure file sharing with client portals: no more attachments, no more risk
At a glance
Email attachment security is fundamentally broken but universally used: Most businesses still rely on email for sensitive file sharing despite knowing attachments can be intercepted, forwarded accidentally, or stored indefinitely in vulnerable inboxes, creating massive compliance and security exposure.
File size limitations and delivery failures create operational chaos: Email servers reject large files, forcing teams into workarounds with multiple file-sharing tools that fragment workflows and reduce visibility into who accessed what documents when.
Audit trails and compliance tracking remain afterthoughts: While regulations demand detailed documentation of file access and sharing activities, email provides virtually no meaningful audit capabilities, leaving organizations exposed during compliance reviews and security incidents.
Why email attachments fail your business
Email attachments are security disasters waiting to happen. A single forwarded message can expose confidential client data to unauthorized recipients. Files sit unprotected in inboxes across multiple devices and backup systems.
Worse yet, phishing scams! These fraudulent emails often imitate clients, partners, or internal team members to trick recipients into sharing login credentials or downloading infected files. When that happens, attackers can gain access to entire email threads, exposing confidential client data, contracts, and personal details.
Because email relies on user vigilance rather than built-in security, one mistaken click can compromise not just one client, but your entire network of relationships. All it takes is one convincing fake message for an employee to compromise your entire network.
The math is simple: 43% of organizations using client portals handle sensitive financial or health data that email simply cannot protect adequately.
What is a secure portal for clients?
A secure portal for clients is a password-protected, encrypted online platform designed specifically for safe file sharing between businesses and their clients. Unlike email attachments, these portals provide controlled access, detailed audit trails, and enterprise-grade security for sensitive document exchange.
They also eliminate common email limitations, allowing businesses to share large files of any format without size restrictions, making file sharing faster, simpler, and more reliable for both teams and clients.
Key differences from email:
Controlled access: Files stay on secure servers, never copied to inboxes
Audit trails: Track who accessed, downloaded, or shared each document
Encryption: AES-256 protection for files in transit and at rest
Permissions: Granular control over who sees what files
For example, thousands of companies use Moxo's secure client portal as it eliminates email attachment risks by centralizing file sharing within encrypted, auditable workflows that maintain security without sacrificing convenience.
The file sharing workflow: now vs then
Traditional email chaos vs secure portal efficiency
Streamlined document collection workflow
Step 1: Send a document request
Instead of sending an email that says “please email your tax documents,” businesses can trigger a secure document request through the portal. This automatically sends clients a customized notification with clear instructions and a direct upload link. Clients simply click the link/button to submit the required files. No email attachments, no confusion, and no security risk.
Each request is tracked within the portal, so businesses can easily see when documents have been uploaded or are still pending.
Step 2: Secure file upload
Clients drag and drop files into the secure portal file upload interface. Large files that would crash email systems, or require alternate tools, upload seamlessly. Real-time progress indicators keep everyone informed.
Step 3: Automated organization and review
Files automatically organized by client, project, or document type. Team members receive notifications when new documents arrive, with instant access to review, annotate, or approve submissions.
Peninsula Visa transformed their visa processing by digitizing this entire workflow, cutting turnaround times by 93% through Moxo's document collection features.
10 critical security features that email lacks
Encryption and data protection
1. End-to-end encryption: Documents encrypt during upload, storage, and download. AES-256 encryption standards protect files even if servers are compromised.
2. Secure transmission: TLS 1.3 protocols secure all data in transit, no more worrying about intercepted email attachments.
3. Data residency controls: Files stay in specified geographic regions to meet local data protection requirements.
Access controls and permissions
4. Multi-factor authentication: Verify user identity before document access—impossible with forwarded email attachments.
5. Role-based permissions: Control who can view, download, edit, or share specific documents within client projects.
6. Link expiry and watermarking: Set automatic expiration dates for shared links and add watermarks to downloaded files for additional security.
7. Restricted download options: Prevent unauthorized copying while allowing viewing and collaboration.
Moxo's security architecture provides these controls within an intuitive interface that doesn't compromise usability for security.
Compliance and audit capabilities
8. Complete activity logs: Track every file interaction—uploads, downloads, shares, deletions—with timestamps and user identification.
9. Automated compliance reporting: Generate audit reports for HIPAA, GDPR, SOX, and industry-specific regulations.
