Deploying a website or web application is a critical step in the development lifecycle. No matter how well your product is designed or coded, an inefficient or insecure deployment method can introduce serious risks—ranging from data breaches and downtime to lost work and broken releases. This is why understanding deployment options is no longer just a developer concern; it is a business decision that directly affects performance, security, and scalability.
For any website development company, selecting the right deployment method is especially important. Agencies often manage multiple projects, work with distributed teams, and deploy changes frequently. Choosing between FTP, SFTP, or Git-based deployment can significantly impact delivery speed, collaboration, and long-term maintenance costs. This guide breaks down these three deployment methods in detail and helps you choose the right one based on real-world use cases.
What Is a Deployment Method?
A deployment method defines how code and files move from a local development environment to a live server. It determines:
How securely files are transferred
How changes are tracked or rolled back
How teams collaborate
How automation is handled
The three most commonly used deployment approaches in web development are:
FTP (File Transfer Protocol)
SFTP (Secure File Transfer Protocol)
Git-based deployment
Each serves a different purpose and maturity level in modern development workflows.
What Is FTP (File Transfer Protocol)?
FTP is one of the oldest and most widely recognized file transfer methods on the internet. It allows users to upload, download, and manage files on a remote server using an FTP client.
How FTP Works
FTP follows a client–server architecture:
A user connects to a server using an FTP client (such as FileZilla)
Authentication is done using a username and password
Files are transferred over port 21 (control channel) and additional ports for data transfer
FTP can operate in:
Active mode – server initiates data connections
Passive mode – client initiates all connections (more firewall-friendly)
Advantages of FTP
Despite being outdated, FTP still has some practical advantages:
Easy to use: Minimal setup and learning curve
Widely supported: Almost all hosting providers support FTP
Good for simple sites: Static websites or one-off uploads
Limitations of FTP
FTP has serious drawbacks that make it unsuitable for modern production environments:
No encryption: Credentials and data are sent in plain text
Security risks: Vulnerable to interception and brute-force attacks
No version control: No history, rollback, or change tracking
High risk of human error: Accidental overwrites or deletions
When FTP Makes Sense
FTP may still be acceptable for:
Personal or hobby websites
Legacy systems with no security requirements
Non-sensitive static content
For anything beyond that, FTP is generally discouraged.
What Is SFTP (Secure File Transfer Protocol)?
SFTP is often confused with FTP, but it is an entirely different protocol. SFTP is built on SSH (Secure Shell) and provides encrypted file transfers.
How SFTP Works
SFTP operates over:
SSH protocol
Port 22
Encrypted authentication and data transfer
Users can authenticate using:
Username and password
SSH key pairs (recommended)
Benefits of SFTP Over FTP
SFTP addresses nearly all of FTP’s security weaknesses:
Encrypted transfers: Protects data and credentials
Secure authentication: Supports key-based access
Firewall-friendly: Uses a single port
Compliance-ready: Suitable for regulated environments
Drawbacks of SFTP
Despite its security improvements, SFTP still has limitations:
No built-in version control
Manual deployment process
Limited automation
Not ideal for large teams or frequent updates
Best Use Cases for SFTP
SFTP works well for:
Small businesses deploying securely
Freelancers managing client servers
Website maintenance with low deployment frequency
It is a secure improvement over FTP, but still not a modern deployment workflow.
What Is Git-Based Deployment?
Git-based deployment uses Git version control systems to manage, track, and deploy code. This is the standard approach in modern software development.
How Git Deployment Works
A typical Git deployment workflow looks like this:
Developers push code to a remote repository (GitHub, GitLab, Bitbucket)
The server pulls the latest changes or receives them via CI/CD
Automated scripts handle builds, tests, and deployment
Common deployment models include:
Pull-based deployment (server pulls from repo)
Push-based deployment (CI/CD pushes to server)
Key Advantages of Git Deployment
Git is far more than a deployment tool—it is a full collaboration system:
Complete version history
Instant rollbacks
Branching and merging
Team collaboration
Automated testing and deployment
Environment consistency
For agencies and product teams, Git is a foundational tool.
Challenges of Git Deployment
Git does introduce complexity:
Learning curve for non-technical users
Requires workflow discipline
Initial setup effort for CI/CD pipelines
However, these challenges are minor compared to the long-term benefits.
When Git Is the Best Choice
Git-based deployment is ideal for:
Medium to large projects
Teams working collaboratively
Frequent updates and releases
DevOps-driven environments

FTP vs. SFTP vs. Git: A Detailed Comparison
Security Comparison
FTP: No encryption, high risk
SFTP: Encrypted via SSH, secure
Git: Secure via SSH keys, tokens, and access controls
Git and SFTP are both secure, but Git provides better access governance and auditability.
Deployment Speed & Automation
FTP: Manual and slow
SFTP: Manual but secure
Git: Automated via CI/CD pipelines
Automation significantly reduces deployment time and errors.
Version Control & Rollbacks
FTP: None
SFTP: None
Git: Full version history and instant rollback
This alone makes Git the superior option for most teams.
Collaboration & Workflow
FTP: Single-user focused
SFTP: Limited collaboration
Git: Designed for teams, branching, reviews, and approvals
Comparison Table: FTP vs. SFTP vs. Git
Which Deployment Method Should You Choose?
Based on Project Size
Small static sites: SFTP
Growing websites: Git + SFTP
Large applications: Git with CI/CD
Based on Team Structure
Solo developers: SFTP or Git
Small teams: Git
Distributed teams: Git with automation
Based on Security Requirements
Low-risk content: SFTP
Sensitive data: Git with secure pipelines
Compliance-driven projects: Git + access control
Can You Combine Git with FTP or SFTP?
Yes, hybrid workflows are common.
Git + SFTP Workflow
Git for version control
Server pulls updates via SFTP or SSH
Pull-Based Deployment
Server fetches latest code from repository
Reduces exposure to production credentials
This approach works well for shared hosting or restricted environments.
Common Deployment Mistakes to Avoid
Using FTP for production environments
Deploying without version control
Making changes directly on live servers
Skipping staging environments
Not backing up before deployment
These mistakes often lead to downtime, security incidents, and lost revenue.
Best Practices for Modern Website Deployment
Always use encrypted protocols
Adopt Git, even for small projects
Automate deployments where possible
Use staging and testing environments
Restrict production access
Document deployment workflows
These practices improve reliability and scalability over time.
Final Verdict: FTP vs. SFTP vs. Git
FTP is outdated and insecure for modern development. SFTP is a secure alternative for simple deployments but lacks collaboration and automation. Git is the clear winner for professional development, offering security, version control, automation, and scalability.
For any modern website development company, Git-based deployment is no longer optional—it is the industry standard. Even if your current setup relies on SFTP, transitioning to Git will improve efficiency, reduce errors, and future-proof your workflow.
