Vantaggi
Established leader in its segment. Engineering oriented culture. As with any large organization your impressions will vary based on locale and who your boss is. Decent comp package and benefits.
Svantaggi
Established leader in its segment that got complacent. The need to move BIG-IP service offerings into public cloud environment has been readily apparent for some years now. They are a classic example of "The Innovator's Dilemma" - company that is being displaced by underdogs and too complacent to act on it earlier. New CEO is driving change by cutting with a sledge hammer rather than a scalpel. This will most likely result in underperformance of current cash cows. The hope is that new offerings will create value faster than damage being inflicted reduces it.
