I have completed the RH413 (Red Hat Server hardening) in the Online Training mode from IPSR and have been thoroughly happy with their services. I can positively recommend IPSR to anyone trying to do the Online RH413 from them. The training and the management staff were very co-operative. The labs provided had good hardware configuration. The support from the IPSR team and the exam practice sessions provided helped me to clear the exam with ease. Thank you and good luck to the IPSR Team.
