Except for Australia, sawfish have been extirpated or only survive in very low numbers in the Indo-Pacific region. For example, among the four species only two (narrow and largetooth sawfish) certainly survive in South Asia, and only two (narrow and green sawfish) certainly survive in Southeast Asia.

The status of the two species of the Atlantic region, the smalltooth and largetooth sawfish, is comparable to the Indo-Pacific. For example, sawfish have been entirely extirpated from most of the Atlantic coast of Africa (only survives for certain in Guinea-Bissau and Sierra Leone), as well as South Africa. The only relatively large remaining population of the largetooth sawfish in the Atlantic region is at the Amazon estuary in Brazil, but there are smaller in Central America and West Africa, and this species is also found in the Pacific and Indian Oceans. The smalltooth sawfish is only found in the Atlantic region and it is possibly the most threatened of all the species, as it had the smallest original range (range c. 2,100,000 km or 810,000 sq mi) and has experienced the greatest contraction (disappeared from c. 81% of its original range). It only survives for certain in six countries, and it is possible that the only remaining viable population is in the United States. In the United States the smalltooth sawfish once occurred from Texas to New York, but its numbers have declined by at least 95% and today it is essentially restricted to Florida. However, the Florida population retains a high genetic diversity, has now stabilised and appears to be slowly increasing. A Recovery Plan for the smalltooth sawfish has been in effect since 2002. It has been strictly protected in the United States since 2003 when it was added to the Endangered Species Act as the first marine fish. This makes it "illegal to harm, harass, hook, or net sawfish in any way, except with a permit or in a permitted fishery". The fine is up to US$10,000 for the first violation alone. If accidentally caught, the sawfish has to be released as carefully as possible and a basic how-to guide has been published. In 2003 an attempt of adding the largetooth sawfish to the Endangered Species Act was denied, in part because this species does not occur in the United States anymore (last confirmed US record in 1961). However, it was added in 2011, and all the remaining sawfish species were added in 2014, restricting trade in them and their parts in the United States. In 2020, a Florida fisherman used a power saw to remove a smalltooth sawfish's rostrum and then released the maimed fish; he received a fine, community service and probation.

Since 2007, all sawfish species have been listed on CITES Appendix I, which prohibits international trade in them and their parts. The only exception was the relatively robust Australian population of the largetooth sawfish that was listed on CITES Appendix II, which allowed trade to public aquariums only. Following reviews Australia did not use this option after 2011 and in 2013 it too was moved to Appendix I. In addition to Australia and the United States, sawfish are protected in the European Union, Mexico, Nicaragua, Costa Rica, Ecuador, Brazil, Indonesia, Malaysia, Bangladesh, India, Pakistan, Bahrain, Qatar, the United Arab Emirates, Guinea, Senegal and South Africa, but they are likely already functionally extirpated or entirely extirpated from several of these countries. Illegal fishing continues and in many countries enforcement of fishing laws is lacking. Even in Australia where relatively well-protected, people are occasionally caught illegally trying to sell sawfish parts, especially the saw. The saw is distinctive, but it can be difficult to identify flesh or fins as originating from sawfish when cut up for sale at fish markets. This can be resolved with DNA testing. If protected their relatively low reproduction rates make these animals especially slow to recover from overfishing. An example of this is the largetooth sawfish in Lake Nicaragua where once abundant. The population rapidly crashed during the 1970s when tens of thousands were caught. It was protected by the Nicaraguan government in the early 1980s, but remains rare today. Nevertheless, there are indications that at least the smalltooth sawfish population may be able to recover at a faster pace than formerly believed, if well-protected. Uniquely in this family, the narrow sawfish has a relatively fast reproduction rate (generation length about 4.6 years, less than one-third the time of the other species), it has experienced the smallest contraction of its range (30%) and it is one of only two species considered Endangered rather than Critically Endangered by the IUCN. The other rated as Endangered is the dwarf sawfish, but this primarily reflects that its main decline happened at least 100 years ago and IUCN ratings are based on the time period of the last three generations (estimated about 49 years in dwarf sawfish).

There are several research projects aimed at sawfish in Australia and North America, but also a few in other continents. The Florida Museum of Natural History maintains the International Sawfish Encounter Database where people worldwide are encouraged to report any sawfish encounters, whether it was living or a rostrum seen for sale in a shop/online. Its data is used by biologists and conservationists for evaluating the habitat, range and abundance of sawfish around the world. In an attempt of increasing the knowledge of their plight the first "Sawfish Day" was held on 17 October 2017, and this was repeated on the same date in 2018.
