SANS Institute offers hands-on cybersecurity training and certifications for IT professionals
SANS Institute is a private company that runs in-person and online courses in information security, network defense, and related IT topics. They do not work for the government, though their instructors often come from military and federal backgrounds. SANS sells certification exams and training programs directly to individuals and to companies that want to train their staff. The courses are expensive — typically several thousand dollars per course — and they move fast, covering material in five to ten days that would take months in a college program.
SANS is known for two things: their GIAC certifications (which stand for Global Information Assurance Certification) and their OnDemand video library, where you can watch recorded versions of their live courses. If you work in IT security or are thinking about moving into it, you will see SANS certifications on job postings. They are not required for most jobs, but employers recognize them as a sign that someone has studied security seriously.
Key Takeaways
- SANS offers live classroom courses, live online courses, and recorded OnDemand videos, each at different price points and time commitments.
- GIAC certifications from SANS are separate from the courses themselves — you take a course, then pay again to sit for the exam.
- SANS courses assume you already work in IT and understand networking, operating systems, or system administration; they are not beginner courses.
- SANS also publishes free security research and maintains a list of the top 25 most dangerous software weaknesses that security teams use as a reference.
How SANS courses are structured and what they cover
SANS offers dozens of courses, each focused on a specific area of security. Some popular ones include SEC401 (Security Essentials), SEC504 (Hacker Tools and Incident Handling), and GIAC Security Essentials Certification. Each course title includes a number, and that number tells you roughly how advanced it is — lower numbers are introductory, higher numbers are advanced.
A typical SANS course runs five to ten days and covers one narrow topic deeply. For example, SEC401 teaches the fundamentals of network security, firewalls, and intrusion detection. The course includes lectures, hands-on labs where you use real tools, and a final exam. If you pass the exam, you earn the corresponding GIAC certification. If you do not pass, you can retake it later by paying the exam fee again.
SANS courses assume you already have IT experience. You should understand how networks work, know what a server is, and be comfortable with command-line tools before you enroll. If you are brand new to IT, you may want to take a general IT course elsewhere first.
The difference between live, online, and OnDemand formats
Live classroom courses are held at SANS training centers in major cities. You attend in person, work alongside other students, and interact with the instructor in real time. These are the most expensive option and require you to travel and take time off work.
Live online courses are taught by an instructor over video conference. You attend at scheduled times, ask questions in real time, and work through labs on your own computer. These cost less than classroom courses and let you stay home, but you still have to show up at set times.
OnDemand courses are recordings of past live courses. You watch the videos whenever you want, work through the labs at your own pace, and take the exam when you are ready. OnDemand costs significantly less than live courses because you are not paying for an instructor's time. The trade-off is that you cannot ask questions during the videos, though SANS does offer email support.
What GIAC certifications are and how to earn them
A GIAC certification is a credential that proves you passed an exam on a specific security topic. GIAC is owned by SANS, so the two are closely linked, but they are not the same thing. You can take a SANS course and not sit for the GIAC exam, or you can study on your own and sit for the exam without taking the course.
Each GIAC exam covers the material from one or more SANS courses. For example, the GIAC Security Essentials (GSEC) exam covers the material from SEC401. The exam is multiple choice and scenario-based, and you have a set amount of time to complete it. You take the exam at a testing center or online through a proctored service.
GIAC certifications are valid for three years. After three years, you need to renew by paying a renewal fee, passing the exam again, or earning a higher-level certification in the same track. This is different from some other certifications that expire and require you to retake the course.
The cost of SANS courses and certifications
SANS courses are expensive. A live classroom course typically costs $7,000 to $8,000 per week. A live online course costs $4,000 to $6,000 per week. An OnDemand course costs $2,000 to $4,000 depending on the course. These prices vary by course and change over time, so check the SANS website for current pricing.
The GIAC exam fee is separate from the course fee and typically costs $300 to $400. Some employers cover the full cost of SANS training as part of professional development. If you are paying out of pocket, the OnDemand option is the most affordable way to get the material and the certification.
SANS occasionally runs promotions or discounts, especially around holidays or for military and government employees. If cost is a barrier, it is worth checking whether your employer offers tuition reimbursement or whether you may have access to for a discount.
SANS certifications and what employers think of them
SANS certifications are well-regarded in the security industry, especially among companies that take security seriously. You will see GIAC certifications listed as preferred qualifications on job postings for security analyst, incident response, and penetration testing roles. Government contractors and financial institutions often value SANS certifications because the training is thorough and the exams are difficult.
That said, a GIAC certification alone will not get you a job if you do not have IT experience. Most employers expect you to have worked in IT for at least a few years before pursuing a SANS course. The certification is a way to prove you have studied a specific area deeply, not a substitute for hands-on experience.
Other security certifications exist and are also respected — CompTIA Security+, Certified Ethical Hacker (CEH), and Certified Information Systems Security Professional (CISSP) are common alternatives. Which one makes sense depends on your current role, your goals, and your budget.
Free resources SANS publishes
SANS publishes research and tools that are free to use, even if you do not take a course. The most well-known is the CWE/SANS Top 25 Most Dangerous Software Weaknesses, a list that security teams use to prioritize what vulnerabilities to fix first. SANS also publishes security whitepapers, research reports, and a daily security news digest called the SANS Internet Storm Center.
If you are curious about what SANS teaches but are not ready to pay for a course, reading their free research is a good way to get a sense of the topics and the level of detail they cover.
Frequently Asked Questions
Do I need a SANS certification to work in cybersecurity?
No. Many security professionals do not have SANS certifications. Certifications help you stand out and show you have studied a topic thoroughly, but employers care more about your actual experience and what you can do. A SANS certification is most useful if you are trying to move into a new area of security or if your employer specifically values it.
Can I take a SANS course if I am new to IT?
SANS courses assume you already work in IT and understand networking and systems. If you are brand new, you should take a general IT course first — CompTIA A+, Network+, or a community college course in networking or systems administration. Then come back to SANS once you have a few years of experience.
How long does it take to complete a SANS course and get certified?
A live course takes five to ten days of class time. After that, you study for the exam on your own — typically a few weeks — and then sit for the GIAC exam. The whole process from start to certification usually takes one to three months. OnDemand courses take longer because you set your own pace, but you can move faster if you have the time.
What is the difference between SANS and CompTIA Security+?
SANS courses are longer, more expensive, and go deeper into specific topics. CompTIA Security+ is a shorter, cheaper certification that covers security broadly. Security+ is a good starting point if you are new to security. SANS is better if you want to specialize in one area, like incident response or penetration testing.
Can I study for a GIAC exam without taking a SANS course?
Yes. SANS publishes study guides and exam objectives, and you can study on your own using books, practice exams, and other resources. However, most people find the SANS course material is the most thorough way to prepare. If you already have deep experience in the topic, self-study may be enough.
